Started reloading 357 mag. I’m getting some pretty big differences in my OAL. I would think it has to be the bullets since my die isn’t getting adjusted but I’m going for 1.590 according to my manual but they are coming out 1.580-1.6. I have never had that much variation with any bullet in any caliber. I have shot Missouri bullets for awhile now in 9mm and 45 ACP and I might get .003 differences occasionally from bullet differences in OAL. With these being shot in in a revolver I wouldn’t think it would be a problem as long as they fit in the cylinder right? These are very light loads for 357 mag. I’m not worried about high pressures at all. These are brand new dies that I took apart and cleaned before setting up. Could something in the die being doing this or just variations in the bullet? All the finished bullets look fine and crimp is in the cannelure. Just don’t understand why such a big difference. These are 158 LSWC from Missouri bullets.
