Re: 7mm STW & 180 gr Bergers
I enjoyed your comment
"But one thing you should do, get a truly flat, as in parallel sides, washer or spacer, and when you back off your die the appropriate amount, insert spacer between die and shellholder, raise ram snug against die, and tighten die. This will help to insure alignment of case to die for resizing."
How about using a brass strip available at most hardward stores and forming this into a flat washer. I don't have access to parallel washers.
any more suggestions
