Just started to load .444. Using RCBS dies. I need quite a bit of force, on lubed cases, during resizing, but the brass looks fine afterwards. Then, during expanding, I am getting a little bulge in the case wall about 5/8" from mouth, just like the lead ball on the expander die is too big. But the bullet will only go maybe 1/16" into the case, that's OK though. It seems to me that the die is resizing a little small. Is it OK to partially resize .444 cases if they will only be used in the same gun? These will be used in my son's Marlin guide gun.
