.257 Shots fired, shots fired, all TAG units within…
the vicinity of Talonairgun.com please respond!
I already told you I was only shooting @ 30 yards so keep your smart ass comments to yourself, or not 🙂
At first I was puzzled by my air situation. I went to the firehouse and I was told by my buddy that he put 4500 psi in my big tank. When he started filling my Joe B. Guppy tank it started hissing at 4200 psi so we figured that was it due to safety valve (have to look into it to see if Joe puts those in his tanks anyone know? Please speak up). EDIT
Just left my guppy tank connected to my big tank for 20 minutes and it turns out that both gauges are working fine. My big tank only has 3900 psi in it???
Why would the firehouse gauge show that it had 4500 psi in it???? So now both CF tanks have 3900 psi in them. Could the firehouse gauges be old and in need of replacement? Perhaps.
One thing though is that when I fill the condor tank directly from the CF tank …when the CF tank says 3400 psi the condor tank gauge only shows 3000. What do you think Doug? Should I try a different gauge on the condor tank….
I tried to move past this first mystery to the next. I am shooting in my backyard 30 yard range (sighting in the SS scope) when I notice that this thing is very tame to my ears. Hell my 24″ .25 condor was much louder!!! I figure it is either lack of air flow or lack of hammer so I go retrieve the chrony from my shed and wouldn’t you know it I was only pushing the 70 grain Lymans at 800 fps. I didn’t realize (despite Doug’s instructions to set the hammer preload to around 2.1) that the preload was at “0” . Since I have no numbers on my frame I grabbed my .25 to compare the position of the screw to. Sent the first shot over the chrony and I knew by the loud bang (although not obnoxious by any means) that my fps had increased…now showing 1,050 (171fpe).
Getting late in the day, yard work to do, son wants to carve some faces into walking sticks, babies crying, dogs whimpering, sun blazing, time to wind things down for the day so I shot a seven shot group with the lyman’s. I shot four shots, then added some more air for the next three shots. Sent number seven from the off hand position and I must say that this gun is a dream to shoot. I expected it to have a more “violent” hammer kick but it does not! It is very smooth. Cocking is relatively effortless and so smooth. I can’t wait to put in some more trigger time but now I have to figure out this “air” situation so please add your “two cents” below, thanks.
p.s. I really enjoyed sighting in with (the first time ever) the Mil/Mil Swfa. First shot was two mils left and 3.5 mils high. Dial my windage 2 mils right and 3.5 mils down and kabowwwwwwwwwwwwww! Bulls eye! Think I’m gonna give this milliradian thing a shot, but for now I am still doping in yards not meters, lol.

80 let me give u a word of advice. Save ur money and buy an airtex comp. Mine takes 5-7 minutes to fill from 3000 to 4500. I know the shoebox is cheap air but they can be expensive. I can’t vouch for the new ones but for a bit more money u will have a lifetime of air. I used my shoebox so much I was rebuilding two to three times a month. I’m not dogging the shoebox at all but if u shoot like me, make the investment. Also the airtex is just as loud as the shoebox. Think about ur decision long and hard.
LOL!
RC shits while on a yellow chair. Pretty funny
Oh, wait a minute, or does he PEE sitting down? 😀
That is some serious air there Charlie! And I like your yellow “port a potty” for when you need to take a dump in the middle of shooting! 🙂
Mike,
Good news is on a single fill, I can get 160 shots at 247 FPE on the Haley using the Hoch nose our bullet.
Bad news it weighs 65 lbs.
Seriously on a 44 cf tank regulated to 3500 PSI I get 35 shots.

Luckily the Dive shop is within a couple miles from my work. I will most likely return to them for a while until I can eventually get a compressor. They fill underwater there too.
Mike,
I was saying that my SCBA tank was NEVER filled completely to 4500 psi and i could always tell cause when i shot my 308 Corsair, i would top off 5x’s and my SCBA tank was quickly down to 3600 psi. Meaning my SCBA was never even at 4500 psi when i picked it up from Sports Chalet. But i didn’t find out till i was in the field the next day.
I know what you mean. Never had one knock the crap out of me, but they have come way too close. I don’t trust them even a little bit. 👿
Tof, that things sounds like an Air Hog from hell. RC’s has to be just that much worse! 😯
I love my Freedom 8 , mostly…..
I really liked the Shoebox but I go from 4500 to 3000 daily on a 44 CF SCBA and it just took too long to fill it. The Freedom 8 does it in a hour or less, is so quiet, I have to check to see if it is running, where with the Shoebox I could hear it from the house.
Now there are some things I do not like about the Freedom 8, well two things.
First that little fan does not cool anything as far as I can see, and yes I tried it with the cover on at 60 degrees and those cylinders got way too hot.
And I did not like the cover on the Shoebox, and I like it less on the Freedom 8.
You have to remove it every two hours, well I do every two hours because I lube every two hours. Not too much of a problem because only the 3 cascaded 66’s ever run the Freedom 8 longer than an hour. But you also have to fish out the end of the fill line to get it disconnected, another thing about the cover I do not like.
So I took the cover off, stored the thing under the bench where the other one was stored before I sold it and put a 12 inch fan in front of the Freedom 8. It stays cool and works great.
I also leave my fill line with the gauge and bleed valve on the Freedom 8 full time. I have a female hand tighten CGA 47 fitting on the end of the fill line and just screw it to the bottles to fill them. The cascaded 66’s have the male CGA 47 connection for this very purpose.
It is sort of a pain to unscrew the CGA fitting each time, and yes they are hand tighten, but it still takes time to do it, I have considered replacing all of them with a nipple on the bottles and a female Foster on the regulator and fill line so I can just snap them on and off.
What keeps me from doing that is I have had a fill line come off a couple times and beat the shit out of me, I have never had a hand tight CGA come off.
Gauges are almost always inaccurate Period.
And now that I have fixed the Freedom 8, I love it more.

Knife,
EXACTLY! That’s why i got the shoebox. I can’t afford a full blown BIG BOY compressor so the shoebox was my only logical option. I can’t live without that thing.
And more importantly like you said, when it fills, it fills a LOT slower so the SCBA tank NEVER get warm or even close to it. Its cold acutally so when it fills to 4600 or 4500 or 4800, that’s what’s actually IN YOUR TANK.
I used to get sooooooo pissed off when i got out in the desert to only fill my Corsair tube up to 3600 about 5 times and the tanks gauge dial would read, “3600 PSI” with the bottle valve all the way opened. By this time, i had only sighted the gun in with 15 shots and my 4500 psi tank would be down to 3600 psi already.
And I understand that in the UK, they are now good for 30 years. Or at least that is what was posted on the Yellow recently.
80-I have had the same problem as you and Tof. Hot bottle when picked up, and 4000 or less when cooled down.
Old Goat sent me a ShoeBox, and it fills slow and steady. And COOL to the touch. 😀 😉

I went thru this a long time ago with a shop. I called the hydro place and asked. Requires a special tool to remove a SCBA valve and there is a torque setting also.
That’s good to know. Then I should not have a problem with it. How many years can you go between hydros on them?
5 years. and, they’re only good for a 15 year lifespan. that equates to 3 hydros. another reason to get your own compressor. ( i’m trying to convince my other half that i need a compressor. so far, it’s not working ).
5 years. I have found some shops are just a problem to deal with.
That is why I had to buy a compressor. I only have one shop where I live and they were a pain to deal with. Always giving me short fills. Got to the point where I would bring my gauge with me when I picked them up. They were filling them out of water where as shops before would put the tanks in a bath tub type tank so they were cooled when filling.
Then there compressor went down so I looked in the phone book for dive shops in the area. Found one 20 min away so I called to make sure he could do 4500 psi fill. Said no problem come on over.
I get there and he says where is the visual for the 4500 and to fill the scuba I need to see your card. That was the first time in the over 15 years that I had been filling the scuba that I had been asked for a card. Always told them it was for Airguns and never had a problem.
That was the end of the dive shops. I left with no air. Went home and ordered a compressor from Jim Sheldon.
Now that I have 8 SCBA tanks and 1 scuba it is nice to be able to fill them. I usually wait until they are all down to 3000 before I fire it up and it takes around 1 1/2-2 hours to fill them all to 4700 psi. Then they are Luke warm and cool to 4400-4500 psi.
If I have the time sometimes I will just fill to 4600 and then go back to the first tank and top them off to make sure I have 4500 psi.

There is no such thing as a visual on a carbon tank. Hydro is all you need to get it filled.

I hear you! I am not on the market for one and won’t be for a few years to come. My .257 will be my last investment for some time. I’m down to just two pcp’s now and both are AF!. I still have my izzy pistol (fun for plinking). Anyway, when the time comes I’ll look into that airtex! Thanks.
