I would stay with the Hodgen Extreme powders for the temp stability. I wouldn't even bother with the RL17. The velocity gain isn't worth the tradeoff in vide velocity variations.
............True! But regardless of velocity variances going from warmer to colder weather, shouldn`t all rifles be zero checked and sighted while in camp before the hunt?
This business about higher velocity variances with certain powders going from warmer to colder weather, is an overrated issue imo.
If ya lose 50 fps or so in the cold, but "ARE" sighted in for that cold weather, then it shouldn`t matter.
I have yet to see any hunter place a target on their game and shoot for groups during their hunts. It is the first shot that matters. And as long as one is sighted in for the cold weather, then using a powder which is more temp sensative shouldn`t matter all that much if at all.
