My 2nd PC is not up right now.

Looking for 280 Ackley Improved
24" Barrel
150 gr TTSX
3.250 and 3.270 OAL
RL-16

I wish they would just host the SW online!

Using GRT it shows max pressure of 65k psi with 55.8 gr. @ 3.27"
Muzzle velocity 3041', Load ratio 98.5%, with 100% burnt powder.

At 3.25" max load is 55.6 gr. giving 3039' MV, 98.7% LR, and 100% burn.

Thank you! I tried downloading GRT on this PC, but it's a work PC and locked down.

I did some manual measurements on max capacity and got 54.5 gr without compression, so that's darn accurate.
