Does anyone have load data on the 280 ackley with 190gr bullets? thinking around 50.0 grains of RL-22 to start. Hoping to get around 2700 fps out of a 28" barrel.
You didn't say what bullet or barrel twist you are using, but you may have trouble stabilizing a 190 VLD in a std. .284 twist like a 91/2.......Rich
Its a 1-9 twist, shot them today. the 280 ackley had no problem stabilizing them, worked up to 53.5 gr rl-22. only had time to shoot at 100 yrds, that said the groups with 52.0 , 52.5, 53.0, 53.5 all shot oversized one hole groups. Plan to run them over the crony next time out, and a 600 yrd test.
