I'm a caster, a reloader and shooter. With times like these when reloading components get hard to find and prices shoot up, I tend to hold on to loaded ammo and components and slows load development of new loads. Ugh! Right.
I am also an air gun (AG) shooter, which is perfect for when the above market conditions exist. The nice thing about AG's is they eat cast ammo great, and low cost pure lead is the allow of choice because of the it being soft.
I just finished this stock, and part of the stock build was replacing the 3000 psi aluminim air tank with a carbon fiber tank, which allows a higher fill pressure to 3600 psi.
Rifle is a .257 caliber Airforce Texan shooting cast bullets ranging from 60 grain up to 93 grain. 1:14 twist barrel. Get longer than the 93 grain and bullets are not stable with the twist rate.
I had some time today and did some shooting over the chronograph to see what kind of speed increases I would be getting.
Here are some performance numbers.
The Arsenal 85gr Spitzer weighing 86gr, are shooting at 1082 FPS / 223 FPE. At 3000 psi they shoot at 1007 FPS / 193 FPE
The Arsenal 257-92 Grain LFN are shooting at 1040 FPS/ 223 FPE
The NOE 258-75-FN HP weighing in at 72gr are shooting at 1128 FPE/ 203 FPE. I backed the power wheel off and got them down to 1090. At 1128 I was getting a sonic crack.
The a 60gr HP and 61gr FN were shooting at 1190 FPS / 190 FPE.
I am shooting tethered to an SCBA tank with regulator between the tank and rifle tank. Standard deviation on a 10 shot string is low single digits.
I am looking forward to getting to the range and trying out the extra speed!
So with the current market for ammo and reloading components it's the perfect time to also be an AG shooter.
