John,

You wrote that you were trimming the rims on .30-30 cases.  My Haenel Original System Aydt swallows the whole .30-30 case with no trimming of either neck or rims.  My Martini is very fussy, but not the Aydt.

Waterman, in this Aydt if memory serves me, I had to reduce the rim 0.003.

I agree with Frank.  I had my best luck with 4227-14grs. This is my Aydt. You might want to try it.

John Boy you need to try the Winchester Large Rifle Magnum Primers with the 300MP none of the others worked for me in both the 32-40 & 38-55.
