Wondering I can full length resize both 7mm Rem Mag and 264 Win Mag with the same die (either one), just by changing out the neck bushing.
Looking at the SAAMI diagram, the shoulder starts at the same 2.040, with same 25° angle. The only difference I see is 2.2459" neck/shoulder junction on 264WM vs 2.2288 neck/shoulder on 7mm Mag.
I have RCBS FL dies for both, but they squeeze the neck down considerably more than necessary, particularly since I open them back up with a mandrel prior to seating the bullets anyway.
What say ye?
