Q:

Test Results. .25

Here are the Test Results as promised using
1. 31 Gr Kodiaks
2. 70.6 Gr 7 Ring Slugs from Jerry’s Kid’s 😀
3. 87.7 Gr. 9 Ring Slugs from Jerry’s Kid’s

The gun is a 21″ Bbl. from Walt. Filled to 2600 psi. Power wheel at 8.8 top hat at .070

Valve is stock. But polished interior. Valve spring retainer has bee ported and polished.

Green Crony 😆

1. Kodiak’s went through the screens at—1020 for a fpe of ——–71.633

2. 7 Ring Slug’s went through at ———–761 for a fpe of ———-90.809

3. 9 Ring Slug’s went through at ———–720 for a fpe of ———100.976

I was a bit surprised that the 9 rings were only 41 fps slower than the
7 Ring slugs.

The nine ring were especially tight. They were VERY hard to seat. To the point that while using the butt of an aluminum knife handle, it actually dented the breach end of the bbl. No way I could seat them with my thumb. Oddly, the Gen I slug’s I had here for testing were much looser. Some were loose, some tight, but none as tight as the new ones.
I will say that the new ones were VERY consistent. Nice work Jerry’s Kid’s! 😀

Now for the accuracy. The 7 Ring Slug’s were spot on. They of course printed lower than the Kod’s as would be expected for over double the weight. T accuracy was much better than expected. And quite a bit better than the Gen-I’s I tested just recently.
I did notice a rapid shift with loss of velocity. AT 2600 Psi, they printed tight for 3 shots, then shifted about 1″ down and slightly left for the following three shots. The first group was tight! The second group opened slightly, but still fantastic for what they are intended to do. The first group fell in at well under 3/4″. The second group opened up to apx. 1 inch.

The 9 Rings don’t seem to like my gun or visa versa. They shot lower again, as expected with their heavier weight. However the group is well over 1 inch. Looks like the 7 rings are going to be the ticket for me and my gun. Shame I didn’t have a few of th 6 Rings from the new batch to try out along side of the others. As it stands. WooHoo on the 7 Rings!!!

All of these groups were shot at 50 yards. About the max I would want to try to take a wild pig. So the groups indicate that in my gun at least, they preform very well indeed! They should be up to the task on any pig hunt with a properly placed shot.

While shooting through the crony, I used a piece of heavy counter top material placed in front of a heavy arrow stop bag. . It was over 1 inch thick and far too hard to drive a nail through. The slugs destroyed it! Giving me a good indication of the kind of penetration that can be expected on tough game.

I know Jerry and others shoot Big Bore air guns on a regular basis. But I’m a newby. even to this medium caliber. If someone had told me a year or two ago that a pellet gun could have this kind of power well I would have politely listened with tung in cheek. 😆 I know I’ve read here time and time again that the .25’s were heavy hitters, But Dam!!!

But we all know a thread without pic’ is worthless, so here we go!

Thanks!

Nope. No lathe work. All done with a snap-on high speed porting tool and different burrs, followed with special cloth polishing cones sold for porting polishing.
And a little elbow grease. 😆
Mike

That is cool for sure thanks for sharing that, now all you have to do is share your secret on polishing looks like lathe work to me? Eddie

Sweet write up Mike,cheers 😀

oooo, looks smooth as glass. Nice!

The vlve is near stock. Condor Valve. I didn’t want to loose too much shot count.

I did port and polish teh valve spring retaining nut for faster flow.

I picked up this trick back in the day when I was porting cylinder heads for drag cars.

I’ll guarantee you hit that pig with 700fps and 70+ grains in the head and the brain is puke!! I have 6 ring and the groups where the same, I was spinnin them alittle faster though maybe I’ll try some slower burners soon.

Mike, beautiful test results and great pics, as usual. Great write up. I bought a stock condor hi-flow valve and was going to mod it to see how much power could be had, but have not had the time to even look at it yet. I turned my own .25 barrel today, though :), in between other projects.

When I have the time I”ll try to get to that valve. If it can be hot rodded into the low 100’s it would be the cornerstone to a really good, cheap setup for everyone to copy, with enough power to take down mid sized game with headshots at close to medium distances. However, this can go on the backburner for now since brad/blod is offering an alternative that is cheap enough for all.

I also have a couple other ideas that need looking into, though. I will keep you posted on them later. Again, thanks for the great write up, and good shooting! Porkie better run!!

So much to do…

Aaah! NITROUS! Better Living through Chemistry! 😈

Or as we use to say out law racing. Better to spray -n- pray than fade away! 😉

Mike

Now don’t go feeling all “back of the bus and s#$%” ! You have a great gun and the results speak for themselves. I think the first 3 shots touching and hitting hard enough to blow through that countertop are pretty good evidence that pigs in your neck of the woods are doomed! Heck, I think that 1″ groups at 50 yards are plenty good for hunting pigs!

I’m just always looking for that little extra bit. That’s why I’ll probably end up putting nitrous on my 502, it sure as hell doesn’t need it for my street driving…it’s just that little extra I can’t avoid wanting! 😆

Oh Man! Now I feel all underpowered and back of the bus and Sh**! 😥

And I was feeling so good about it! 😆

Seems to me that the six rings might be a good choice for some as well! 😀

Mike,

Yes, I know they work, lot’s of folks have mentioned that! 😀 I was curious how they would work in your gun as it is not set up as the max power gun that the slugs were really designed for. Because of your test, I can safely recommend the 7 ring slugs down to a gun that shoots Kodiaks at just over 70 FPE and I can also take into account a 21″ barrel at that power level.

The slugs were designed for that small group of folks shooting Condors that had been modified with big valves, heavy hammers and found that they were over-driving the Kodiaks and needed something heavier but the market didn’t have a good slug for them. Since then, I’ve fielded many emails from guys with guns of lesser power asking if and which slugs to buy. It is always nice to be able to point to actual results instead of saying “I don’t know” or take a chance…

As of right now, I can recommend the 7s down to a lot more guns but I will hold the recommendation of 9s to full boogy long barrel guns (except for plinking stuff that blows up nice)!

Thanks Guy’s! 😀

Hey Jerry! No doubt I Can get another 10 lbs our of her. the only thing stopping me is that it is set now and doing just what I want. Perfect for the Kodiaks. And with only a slight scope adjustment, perfect for a little pig hunting. If I ever get a good CF tank, I’ll be able to give her a full 3000 psi charge. That alone would pick her up a bit. Along with a heavier hammer and whamo! Mini Elephant (pig) gun! 😯 😀

They say that more is never enough, but she is doing more than I ever expected!

Jerry-THEY WORK!!! 😉

Mike

Pretty damn sweet! 😀

WoW!!! nice groupings…mostly the Kods= )

i gotta try the slugs someday…unfortunately i havent even gotten the chance to try the Kodiacks…one more month to go! 😀
