Home Forums Reloading Big Game Rifles 280 Ackley Loads with Barnes 140 Grain TSX or TTSX

For reference, I used 53 grains of R17 in my 284 with the 140-gr TTSX at 2.95" OAL an hit 3150 fps out of a 23" tube. This would shoot .5 MOA at 400 yds but made me a little uneasy so cut to 52.5 and 3050 fps.
