I have a particular hunting load for my 6.5x 284 Norma that I have used for years. Long story short, a particular load of IMR 4350 shot great last season. Stored the ammo In an ammo can in my climate controlled shop(never under 60 never over 80 Deg F) after last deer season. Grab the ammo and head to the range to shoot. Rifle is clean. First round I chamber feels tight. Pull bolt back, bullet stays in rifling, powder everywhere. Clean mess up, shoot 3 and it happens again. Go in shop and run all cartridges through seating die. About 1/3, of them I could feel move. Shot over 200 of this batch last year and never had so much as a sign of a problem. Never had this happen in anything else I have ever loaded or in factory ammo I have stored forever. IMR 4350 was about the only powder I used for my first 15 years of reloading. I have 257 Wby IMR 4350 handloads over 30 years old stored beside this ammo and they are fine. I still have the 8 Lb jugs the 6.5x284 was loaded out of, stored in same shop that by visual and smell test is still fine.
