[QUOTE="lancetkenyon, post: 1467108, member: 68875"] I FL size every round and bump shoulders .002", belted mag or not. All of my rounds are hunting rounds, so I want them to chamber smoothly. No real difference in resizing a belted case than a non-belted case in my opinion. A quick comparison between .280AI & 7RM (I have both): .280AI 175 Berger Elite w. 58.0gr RL23 @ 2975fps 160 TMK w. 61.0gr H1000 @ 2940fps 7RM 184 Hybrid w. 69.0gr RL26 @ 3065fps 180 Hybrid w. 69.0gr H1000 @ 2996fps 168 HVLD w. 69.0gr H1000 @ 3070fps With similar powders, you burn about 10-15% more powder for 100ish FPS. You can always load your 7RM DOWN to .280AI velocities, but not vice versa. But either will serve you well in a hunting rifle. [/QUOTE]
