It's my go to powder in the 25.06! I've been using it for years in this caliber with no problems what so ever even when changing from mild temps to cold temps. I also haven't experienced the change of velocity with it either but then again the 25.06 is all that i use it in. I don't own any magnum rifles so it may well be different with those. I also like 7828 in the 06 and have a couple nice loads worked up with that as well.
