I'm about to buy a carbon bartlein in 7mm for a long action build. Want 7mag+ performance w/o a belt. 7 Sherman Mega and 7lrm are up for debate.
Who using the ADG/Gunwerks 7lrm brass? Utilizing the gunwerks Hornady Match bushing dies? How much does the web area get sized by dies after 3- firings?
Trying to figure if the GW bushing dies are specd properly to the hard sizing resistant web area that ADG gets a habit of after a handful of firings. The 0.200" line on the 7lrm chamber is 0.533, the same dimension that gives problems in saami 65/300 prc chambers.
