For this gun (Ruger American). Did you happen to measure one of the bullets in the magazine after shooting one? So put one in chamber, one in magazine, shoot one in chamber, and take the one out of the magazine and measure it for overall length? Just wondering if the crimp is strong enough to keep recoil from causing the bullet to creep (in or out).
Texas Sheepdog: I see you have an RCBS press.. One of the reviews for the Hornday dies on MidwayUSA says that the seater die only gets one thread of engagement when set to seat the bullet. Do you have the Hornday set, and does it work ok on your press?
I run an RCBS Supreme and Hornady 450B die set. I have no issue with the dies not threading down far enough. However, I have a Hornady 7.62x39 die set, and the seater die only goes in 1-2 turns before crushing brass. The 7.62x39 sizing die also sizes the case head down WAY too much. Not happy with that set at all. No issues with the 450B set, though.
