[QUOTE="Mike Matteson, post: 2907156, member: 101791"] Thank for info. I have downloaded it into my Temp folder. Anything on H4350, H4831, and H1000 for data sheets like have forward to us. I watch all the time for info on Temps. I have hunted in weather from -20 to 110' over the years. I generally use H4350 powders. Found it to be very stable. Well over 20yrs ago I ran into a problem using IMR 4350, and IMR 4831. I develop a load for a rifle in the winter time in So. Cal. Temp was around 50'+-. Went back to that load in the summer. Weather was around 100+. Same powder load, and below a primer out of the case, and a very stift bolt. Figure it out that temp was a big problem with those powders. Never used them again. Scared the hell out of me. Gave away 16+ lbs of powder. Some of the powder in your chart are single based pwoders. In all the reading I have done over the pass few years. Double base powders have more problems with temp than the single base powders. A little more input. I generally load over the manual top load. Depending on what powder and pressure signs show up. The IMR 4350 I was 5+ grs over and the H4350 I am 5grs over in powder. Lost 100fps between the two, but never had any problems with the H4350. Found it to very stable in weather from -20 to 110. I hunt or hunted in So Cal, Az Colo, Wy, Nv, MT, & Idaho. So like you I see some big temp changes. I always try let people know about the temp powders. Some get mader than hell about it. Especially when they are pounding there chest about there powder loads. [/QUOTE]
