Not enough powder, I'd consider 70 as a minimum, and 75 a good working load.  Use Fg, that will also help.  Quite some time ago I did some extensive experimentation to determine what works and what doesn't as to accurate loads.  If you PM me your email, I'll send you the document that kinda summarizes my trials.

ok, not 65gr.  i'm just punching holes in paper for giggles. i thinking along the lines of the carbine load.

This might be a fevered dream but, i think someone mentioned using a "460 rowland" die as a neck size?
