[QUOTE="Mike Matteson, post: 2682518, member: 101791"] That the way I see it. I have major temp swings so I am stick to H powders. I generally use H4350 or H4831SC. I haven't noted any notable change in taking animals. I hold my shoots to 500 yds and under. At a 1000yds, Velocity variation of just 30fps changes about 8.5". A 50fps variation can change it by 14" at a 1000yds. Some powders have as much as 125fps swing and that from 0 dr to 120dr.. Take it another 20 dr lower. Bottom line is that you need to know what your rifle does at different temp. The chart I use for H4350 is 4fps variance in the same temp range. Now I didn't get the same velocity out of the H4350 over IMR 4350 by 100fps. [/QUOTE]
