[QUOTE="QuietTexan, post: 2237138, member: 116181"] I think the powder will be too slow to make you happy with the results. 307 Win, which has ~5gn less water capacity than the 308 Win, maxes out at 46.0gns for 2429fps behind a 170gn Interlock. I was surprised when I checked the SAAMI book to see they listed the same max pressure for each, considering the 307 Win is a lever action case, but apparently the case walls are thicker. 52000 CUP for both the 307 and 308 WIN under the crusher data. 308 Win is 62000psi using a transducer, but that works out to 52000 CUP. [B]PSI[/B] = -17,902 + 1.516 x [B]CUP[/B] [/QUOTE]
