[QUOTE="Mike Matteson, post: 2449958, member: 101791"] To start with I never used Ramshot Hunter Powder. Here what I have ran into over the years. I develop some load with IMR-4350 & 4831 powder in the late winter in Mexico-North, (AKA Calif) Temp was about 50 to 60 during those days. Develop 3400fps with 165gr bullets. Changed over to a different rifle and loads. When back in summer. Temp was 90 to 100+ at that time. Pickup up the first rifle to shoot. Blew the primer out of the case first round out of a cold barrel. Need to say that ended the shooting for that rifle that day. 49 round to unload. Figure out IMR powder don't like temper change. I switch to H 4350 and H 4831 powder. Now I didn't quite achieve the same velocity with the H powders. I end up @ 3300fps. I hunt in weather from -20 to 110+ temp. I never tested that load to see what change was with where it hit in different temps. I never had a problem in shooting out to 500yds with the H powders in any type of weather or elevations. It probable does, but I didn't note it. I gave away about 16lbs of IMR powder, and never looked back. What I am saying is be careful and test your load in different temps. The other is lots of my loads are about 5grs over what the loading manual calls out for max loads. I look at accuracies and velocity. [/QUOTE]
