Been disassembling PPU ball ammo, to harvest the brass, ahead of a reloading project.
Rifle is a 6.5x55mm Ruger Hawkeye African 24"/1:8 Bbl., currently aperture sighted.
Tentative powder/primer selection is IMR 4831/CCI 200 respectively. (recommended, and is also used for the .270 Win/150 gr. load)
Bullets are .264/140 gr. Speer Grand Slam (current production), w/ an eye out for some of the new .264/130 gr. Barnes TSX-BT.
So, two basic loads.
Would like these loads to be at or near .30-06/M2 pressure - 50K CUP/60K PSI, a/o 2800 fps at the muzzle.
Hodgdon Reloading Data Center says 46.3 gr. of this powder will yield 2700 fps, remaining w/in the anemic SAAMI spec of 46K CUP/51K PSI for this cartridge.
Figure (extrapolate) ~ 48 gr. should yield ~ 2800 fps, and still be under the 50K CUP/60K PSI limit.
Would start the ladder at ~ 46 gr., chrono'ing above maybe 47.5 gr. and paying a little attn. to group size.
Figure the 130 gr. TSX would used the same final charge, albeit w/ a different velocity.
Questions/Comments/Concerns appreciated.
