[QUOTE="Lefty7mmstw, post: 685962, member: 48043"] I'd get some wc 872 from wideners and work it up with a chronograph to the old Hodgdon #'s with a 140. Most mid-magnum powders will leave a lot of room in the case in a 264. It's worse than a 7mm stw in how slow you really have to go to get top speed with it. If 872 doesn't float your boat, then I'd go with rl25, or retumbo. I just checked Hodgdon online and they don't have data for any of the BMG powder for the 264 anymore. Hodgdon #26 h870 data was as follows: 129 grain--h870--- top load--76 grain-- no start load listed. speed-- 3170 fps 140 grain--h870--- top load--73 grain-- no start load listed. speed 3163 fps 160 grain--h870-- top load-- 68 grain-- no start load listed. speed 2868 fps H870 and 872 are very similar powders, but you do need to start 10% back and work to pressure. I'd use the heaviest bullet I plan on using to put load on this powder as it get's less stable when it isn't loaded. The real kicker here is with the 140 and 870 type ball the 264 will run with the 7rem with a 140 that is a lot better ballistically. [/QUOTE]
