Re: 338 Remington Ultra Mag load data desired
Another load test tonight in the 338 RUM.
I tried 90 grains of RL25 over the Fed 215M primers and the big 300 grain Sierra MatchKing. (Load Density 100%)
OAL 3.650 (magazine limited)
Four rounds over the Crony:
No pressure signs on any case, first round was cold bore.
I tried the 300 Sierra MatchKing on a crop damage deer at 200 yards, pretty devastating.... it was a bang-flop proposition.
BTW, water capacity for once fired cases, 111.3 grains (water to top of case, primer in backward)
