Quote: Brno ZKK 602 rechambered from H&H WW cases 350-grain PP or RN CCI 250 primer 81 grains IMR 4831 COAL 3.585" 2400 fps 25 yds -0- 50 yds +2" 100 yds -0- 200 yds -4" 300 yds -10 to 12" Tried W760 with RHINO 350 and 380 grainers before (75 to 76 grains). 72 grains IMR 4350 with 380 grainers yielded 2260 fps. I do NOT "push envelopes" so go further if you like. The IMR 4831 is compressed and the W760 not. Barry Nagel |
