It’s here!!
After a couple years of wanting it I finally bought a .300 win mag barrel for my blaser a couple of weeks ago. After anxiously waiting for what seems like forever, I got the first of the two packages. 😀
Got my muzzle brake and mirage band today. I knew the muzzle brake would be big, but the thing is huge. 😯

I always knew how they worked to reduce recoil, but I always wondered how much they do to reduce muzzle climb/flip. I don’t know if they are all like this, but this one has been very well thought out and has a nice design to help that as well. You can see the way the bottom is much wider and has a slowly sloping v shape to keep the muzzle down. The top is much thinner with a sharp v.

I haven’t used many brakes before. While I was looking at them online I noticed there is a huge variety in price. This one was at the very top of the price list. This is the one that my blaser dealer sold and told me was the best for it, so I figured I was spending a lot anyway and I may as well get it. I’m curious how much better it will be than one of the cheaper ones though. It looks to be of extremely high quality, so I’m sure I won’t be disappointed. 🙂
More pictures to come tomorrow(hopefully) when I get the barrel and other parts. 😀 😀 😀
I’m like a kid before christmas. 😯

Only being able to shoot off about 5 rounds before the barrel gets hot, yeah, it takes a LOOOONG time to shoot. I shot 40 rounds one day without getting the barrel too hot, and I think I was out for 7 hours. 😯 That is the nice thing about the .22lr though, you can shoot it while you wait for the other gun to cool.
I decided to hold off on reloading. Since I’m shipping out in January, I don’t want to get into it and start learning just to have to quit soon after. So after I finish up with my military stuff I’ll definitely start up. Just doesn’t make much sense to start right now.
lookin good
Yep, went from 2″ to under 1/2″ at 100 yards.
I’m not sure he can afford to reload after buying that barrel… 😯 And the mere 70 rounds per pound of powder he will get… 😕
I’m kidding, Lama, reloading is half the fun!! Or more! I love it!!! 😀 It’s funny though, I always thought I could burn through 100 rounds easy in a range day. If your letting things cool and tracking shot strings and recording info in the log book it can take hours!
quit buying that factory stuff and load em yourself. 😉
lookin good
Finally got used to the recoil and noise, so I sighted in today and finally had half decent groups. 😆
Most of the groups prior to this pretty much sucked. I wasn’t used to the new level of noise and I was flinching a bit. Groups weren’t horrible, all of them were under an inch, but not nearly what I wanted them to be. Today was better though.

Crappy picture, but you can see several groups there. Moved around from sighting in, and the last group is in the red. The red circle is 1″ wide. So I’m happy with this. Just factory ammo, federal premium. The groups should tighten up a bit with match ammo, which I plan on getting sometime soon.
And now that I can shoot it, I need to find somewhere to reach it out a bit farther. 😀
oops sorry didn’t mean to call you the wrong name Roach . Lama you gonna get to loading , what did you decide.
Powder Burner,
He could still shoot small groups after 580 rounds, and did for a couple of hundred after that, But he had to load them out to touch the lands, effectively turning the 700 Remington into a single shot. He still has that rifle and many more like it, but I have no idea what the count is on rebarrel jobs.
My philosopy on the matter for years was that barrels are cheap, especially on the 700 Rem because it was so easy to buy a douglas air gauge and rebarrel. But Lamas gun does not share that luxury,
I shot a lot in my youth, I was crazy about guns, I retired with a full tax free pension at age 31 in 79 after two shooting incidents and a career changing inury and devotred myself to shooting.
I lived for 13 years in the only house in 110 square miles and had a 1100 yard range with a bench rest at one end and a 700 lb steel buffalo at the other. I had a complete steel combat reactive course set up. I had just about every long range gun you could think of from one of the first SR25’s to a 30 inch 45/100 Sharps Borshardt.
I conservatively fired 5000 rounds of big bore rifle per year, it took 8 hours each week at the reloading bench, not counting casting bullets to keep up with it.
And it was in the middle of some of the best elk hunting on the west coast, not to mention the deer and bear hunting, sage rat and jack rabbit hunting. If it moved I shot it, I killed hundreds of mule deer and 50 elk and a handful of bears, including one off my front door step.
I could ride a horse for hours in any direction and never come to a house.
As a result I hate to reload now, I am burned out, and my hands no longer can grip those cases to feed a Dillon 550 much less a RCBS press. I love these pellet guns, I can shoot them here on the vineyard and nobody is the wiser, but for years I experimented and burned a lot of powder and read every magazine I could find. I wrote two books on that mountain also.
I was lucky, I lived in a time where we had the freedom to do that and I lived in a country I could do it in and had the finacial resources to afford it.
My doorjam was blackened by the scourching flame of 44 mag cylinder blow by, and my hearing shot from surpirse shots at fleeting targets.
And I loved it. But we get old, the last 3 years there I lived as a hermit after my wife left with my children. I gave them every cent I made, keeping $200.00 for myself for three years and lived off of rice and beans and what I could shoot on the hillside. I meditated and I mourned the loss of my children.
The last year was the worse, my battery bank for my underground solar electric house, 20, 6 volt batteries wired up to 24 volts, gave out and I lived in the darkness after 4 pm in the winter except for the glow of a gas light. I meditated and did pushups and effectively lived in a prison that was once my paradice.
I finally divorced her and dedicated that house to a hunting camp and bought a very nice spread close to town, 4000 square ft house on 50 acres with a three stall barn and riding arena. I moved my targets and my horses and continued shooting and riding, but with only a 200 yard range, and I eventually got my kids back from that crazy bitch and finished raising them.
So yes I have had an interesting life, and I continue the adventure now by traveling, I still shoot somewhat, I am a member of a idpa combat club in the Philippines and of course have a growing arsenal of pellet guns. I gave my PB’s to my children when I came to the point I could live among people , I moved again and started buying airline tickets.
But still I get a little amused and as you have noticed, sometimes cranky at folks who come into sporting good stores to buy a box of deer bullets or scratch their heads in wonderment at the term Over Bore, and wonder if such a thing exists.
And no, I do not write under the pen name of Riverside, that one is a give and take situation, I know only about 10% of what Riverside does, however I am far better looking and easier to get along with. 😆

Hey roach i didn’t say you were full of shit or didn’t know what you were talking about , and in way few words i basically said the same as you,
butt you are not right on with your 500 round barrel ware out either.it would be possible, but dam man after 3 rounds you almost cant hold your hand on the barrel. and that’s down closer to the muzzle, you cant toward the chamber.
If a barrel is not allowed to cool , it will deteriorate allot quicker,
you would have to load and shoot quick and not worry about barrel heat to ware a barrel out in 500 rounds man. i don’t shoot em any faster than i can keep my hand on the barrel. I agree about throat ware, and i am very aware of it.
what kind of rate of fire are we talking about to ware a barrel out in 500 rounds,and usually a top accuracy load will not be maximum charge anyway.
Do you know how many rounds that he shot each session and how long for the rounds to be fired.was his barrel smoking or what.
I am an accuracy nut and have been loading for this since the beginning.i have always took my time on the bench, and always will. i like em all touching.
you will have to excuse my lack of experience, and as far as research , i have been living this shit since i was 16,17 , and i will never know it all, i do know that i will never quit learning. i know that i am still wet behind the ears compared to allot of you guys, and i have only been reloading for 20 years.
Hell i wish a could shoot enough to ware out a barrel. when i go to the range i usually have several guns to shoot and try loads so i dont put a crazy amount thru any one rifle. Cant really tell you total round count on my belted mags, 7mm , 338 , . and i never have built a heavy bench gun.
All my mag guns are sportsters and they kick the hell out of you, so you really don’t have to worry about shooting them too much. I am surprised that lama has already put 60 rounds thru his.That muzzle break must really be something.
you know now that i think about it, I was at the range a long while ago shooting rifle and two younger kids and there dad were shooting on the other end of the firing line, i noticed when i was busy shooting that the percussion was pretty intense, and when i took a break i walked down to see what they were shooting.One kid was about 10 and the other maybe 14 , and they were fairly small , i stood behind them and watched for a minute and man the blast was crazy, you would of thought they were shooting 243’s for there size , but the small one was shooting a 7 mag and the older a 300 mag.
They had muzzle brakes on the rifles and they said the recoil was about like a 243, that they had shot before. but the blast was terrible
And yes Lama you have to make sure you have plenty of padded surface around your shooting bags for when the rifle comes up and off the bags with recoil.without the brake anyway.
I always wore a football mouth piece or took a piece of cardboard and put it in my mouth between my teeth when i was shooting the heavy recoil stuff , because i would relax so much when shooting for groups that it would rattle my teeth.and i always wore double ear plugs .
well i suppose if you want to hurt the barrel, shoot the hell out of it, and don’t Waite for it to cool , i figured most had the good sense not to keep shooting until the barrel started to melt.
roach i enjoy reading your post and am not trying to take away from you , but there are a few of us out here that have put alot of rounds down range also.
Popwder Burner,
It’s Roachcreek not Riverside.
Ignorance is a nuclear scientist who is out of his field, it is not an insult it is a fact.
This stuff is rilfeman 101, if you do not know about it already you soon will, sorry to be blunt, but your showing your ignorance when you doubt this, all the great rilfe shooters/writers have written about this for years.
Yes he, Alan, loaded it very hot and wasted that barrel on the bench instead of in the field where they need to be shot. But he followed Mcmillans advice, and that is the same Mcmillan who developed the m40 sniper rifle for the USMC.
When the throat goes, and that is what happens, the accuracy will go fast. Look at it as a dry lake bed that is cracked and checked from the heat of the sun. Then a wind comes up and blows the little squares away.
That is throat erosion, and sorry to burst your bubbloe, it happens to all over bore barrels. I had a 7mm mag that went in the same round count, but news flash here lama, I was only getting 3 shot per peice of brass because of how hot I loaded it, and how fast I shot shots in grouping and competition. It was 30 inches to start with, when the throat went, I had it cut to 24 from the chamber end as an experiment to see what would happen. But alas it never shot good again, the entire rig weighed 15 lbs, we called it the telephone pole gun, and it would shoot 1.5 inches consistantly at 300 yards, not just a trophy group once in a while, but all day.
Like I said, heat is your enemy, when it is hot, it is like that dry lake bed, and the chamber pressure of hot rounds combined with that heat causes little squares of metal to blow away.
Overbore simply means you have too much powder for the barrel combined with too much case for the barrel, the 308 and the 223 will last for thousands of rounds, the big mags are a heart breaker tho.
So powderburner maybe you should research before you put you opinions out there? This has been shown to be a problem since the 30’s when 220 swift came along, and then the 264 mag. All are over bore andoall will do this. YOu can shoot groups slowly to postpone this a few more hundred rounds, but I doubt you will see 3000 rounds of the degree accuracy you want.
And again when it goes it goes fast and shows up as flyers in your group.
Ball powders that burn with somewhat less heat help but not entirely.
Read up on it boys. There is wealth of information out there and poo pooing it is only putting your head in the sand.
I used to have a stack of worn out barrels in the corner of my gun room.
And yes we cleaned them, and we did it correctly, and by the way, the guy who wore it out, is a top shooter, he has forgotten more about rifle shooting than you collecctively know and still knows twice as much as all of you. He is crippled, but when he feels good, he outshoots younger shooters and did it again last month. He has a gunsafe full of very expensive tackdrivers.
In the 80’s we had a forerunner to practical rifle shooting called OPSA, when Alan did not win the State Championship , I did, Alan had the state championship 3 or 4 times, I won it in 81 and 85. Missed it by less that 2/5ths of a point for the year in 83 to Alan. So yeah we went thru some rifles, but this bolt gun stuff was just a side shoot.
Your average deer and elk hunter willl say that he has shot his 300 for twenty years and nothing bad has happened, and he is right. He will shoot a box or two every year, and it will take years to get to tis point for him, and then it will show up in ways he will not detect, in that flyer I talked about, and for the deer and elk hunter one flyer at the bench sighting in before the season is no big deal.
But for us accuracy buffs one shot 3/4 of an inch out of a half inch group at 100 yards is a big deal, a very big deal.
When you shoot thousands of rounds a year like we did and read everything you can find like we did you learn this stuff. It is an education and education does not come cheap.
You think I am a alarmist, do you want to find out the expensive way?
Roachcreek
how many times did you clean that sucker in those 60 rounds.
And what are you going to do about the reloading set up.made up your mind yet.
Haha, probably a good point. Looking at other stuff online, people are saying plenty of shots for what I will be able to do. Most of the comments was thousands of rounds before starting to notice wear. Roachcreek, your friend must have really done something stupid to wear it out that fast. I don’t think even the hyper velocity rounds wear out barrels that quick.
Plus, blasers are renowned for the extra barrel life they have due to the extreme hardness of the barrels. So as long as it should last, I have been told to expect a good portion more from my rifle.
And I freaking better get plenty of shots from a barrel I payed $2200 for. 😯
Come on guys you know better than that, river side is real close but i think he is trying to spook you a bit.
heat and rate of fire,
rule of thumb is you will degrade as shot count increases. but we are talking 1/4” to 1/2” MOA after 1500 rounds to 3000 rounds , unless you hot lap that sucker, then we may be at under 1500.
You hope you get to shoot that 300 Winn mag enough to ware out the dam barrel. cost and time , don’t think you have any thing to worry about.
If you do get to shoot it that much you can always have the barrel cut and re chambered.
barrel’s are a consumable item. on a belted magnum , for sure
Well thats gonna suck the wad if you do only get around 600 rnds from it 😯 😥
580 rounds! 😯 I refuse to believe it is that short. I have put 60 through it already, and I’ve had it for just a week!
My head is still ringing (not my ears, strangely enough they aren’t) but my head feels a little off balance. 😕 😆
Next range trip will be next week. Meanwhile I’m going to do lots of dry fire practice. 🙂
Lama,
You do know that 300 win mags have a short barrel life?
I had a friend who went thru his first Macmillan M 40 barrel in 580 rounds, he loaded them hot, he could still get good accuracy by loading his bullets to touch the lands after that, but they would not feed thru the magazine.
Heat is you enemy here, shoot slowly keep the barrel as cool as you can and you will lengthen his 580 rnd life by a few hundred.
I have owned several 300’s, I love them, I killed many elk with them, great elk medicine with 180 Nosler Partitions. The Nosler store used to be 150 miles from my house in the nearest big city of Bend Oregon, I used to buy seconds there very reasonable.
Last year I had lunch with my boy and the Navy seal, in charge of training all the Philippine special forces, in Manila. He was in love with the 300, he used it both to hunt with and to kill with. He told of snipers killing at beyond a 1000 yards, on walking targets, which is no big deal, but they were in the back of a Humvee when they did it.
It is a great round, I prefer the short mag because it does not have that belt, when you start reloading you will find out what I mean by that.
Enjoy that fine equipment.
By the way, I used to have a 6 lb 340 Weatherby, great gun, I found that if I wrote my name and address on my forehead I could always get someone to take me home from the range. 😆

better accuracy , almost guaranteed.
self gratification that, “Hey, i just loaded that round”
besides its fun.
