So I am loading Sierra 69gr. HPBT for my SPRish AR and the manuals using that exact bullet recommend seating to 2.260" which I am aware is max for mag length.
I had always thought, since bullet tips can be varied slightly, that you seat based off of the shortest projectile. Obviously when I do that all others come out over mag length.
I guess my question is, how much play is there in seating depth for a load like that? Do I need to measure each OAL (huge pain) or should I set my die based on the longest projectile? Obviously people load on progressives and it would be crazy to check and re-seat each and every one.
So If I set my die to seat the longest at 2.260" and most others come in somewhere around 2.256"+ am I still good? I am working up loads starting from minimum charge for now.
Is there a preferred seating depth for a load like this or should I keep it close to mag length?
