[QUOTE="Mike Matteson, post: 2681447, member: 101791"] Yes I did over 20 years ago. It was IMR 4350. Set and had an excellance load doing 3400fps in the winter time in Mexico-North (aka Calif) which wasn't that cold either. In the 50+drg. I went onto other rifles and loads. In late June I changed back to my rifle that I had develop the load for. Temp was about 100deg. I had a hell of a time getting the bolt open. Blew the primer out of the case. Change to H4350 and never looked back. Lost 100 fps, but that was ok, and the groups was about 1/8" overall wider. Move from 3/8" to about 1/2" groups. Bottom line I gave away 16lbs of powder and never used it again. Was I pushing the limits on the loads "YES" Most double base powders have temp problems. Look at what SD & ES devilation in changes in velocity. Under 500 not so such a big deal, but at longer rangest it can be a hit or a miss. That also depends on what you are shooting at too. [/QUOTE]
