The minimum chamber is fine for sure, quite nice actually as all I do is neck size. The tight neck is okay as well. It is just these 35 cases, the rest are in top nic, so i can re-learn a few brass handling skills and then use them for practice/plinking.

I have formed a few R-P 8x57 cases and they are too thick as well, by .001" with a .366" Speer.

thanks for all your help/info so far Daryl,
