Cheddite hulls

[Austin J Hawthorne Jr.]

Have you tried adjusting the sizing collar? I've been loading RST 16 gauge hulls for years on a MEC 600 with the short kit and have never experienced deformed brass. However, when I first started using the short kit, I had an issue with the sizer not resizing the brass all the way down to the rim. As for the crimp memory with cheddite hulls, after 2 - 3 loadings they seem to settle in pretty well for me.

I reload Cheddite hulls for 16g 2 1/2" on a MEC 600 with a short kit. No issues at all unless I try to load paper hulls. That has about a 90% success rate. Always wind up with some buckled hulls. If I am loading 16g 2 3/4" I roll mine with Fiocchi hulls. They load very nice and never give me a problem.
