I've loaded a thousand of them in 38 SPL +P loads (5.5 gr Unique) which gave 980 fps out of a 4" M15 and 1010 fps out of my 5" M15.
I TL'd them with a light coat of LLA and let thoroughly dry before loading. I seated and crimped with a medium crimp almost exactly as the picute posted by Texas by God shows. With the additional coat of LLA I got no leading. Expansion was excellent and equal to the Winchester and Federal +P LSWCHP factory loads in sopping wet newsprint. I developed that load to equal the velocity of the factory Win/Fed +P loads back in the 70's. Recent pressure testing (Oehler M43 PBL with a Contender test barrel) shows the psi is within SAAMI +P MAP for the 38 SPL.
