So today I decided to do yet another 308 Win test ...
308 LC primed brass to see what was possible with this cheap brass.
test rifle, 308 W 22" 9 twist Bartlein with 2.980" mag
155 Lapua scenar 3098 fps with 2000MR
225 ELDM 2543 fps single feed good load
208 ELDM 2549 fps ...fit my mag. good load
230 Atip 2552 fps ave ..one went 2588 fps
230 gr SMK 2486 fps ...good load low S/D
250 Atip 2319 fps, did not load with enough powder to hit the top velocity.
18" AR 10 ..with a few rds
225 Eldm 2455 fps good load consists.
250 Atip 2219 fps ...2 grains down no full charges left to try, plus just for fun..unstable.
The 30" 8 twist LC brass 155 scenar had a velocity of 3220 fps.
A bunch of other loads were tried in 18" AR, 22" bolt, and 30" bolt to compare velocity with bullets from 130 to 250 Atips. The 230s 225s bring the energy high BC in the 8 & 9 twist, with cheap throw away brass, and the 22" 9 twist is versatile...the .8 BC 230 SMK was accurate and consistent, and more powder can be added under it to match the 230 Atip, to get the 2550 fps. Plus I have Lapua cases SR & LR, and the famous reformed bimetal 277 Fury cases to 308. An interesting and productive day...you can go cheap and still play.
