Any AR platform will allow the firing pin to hit the primer upon chambering a round & leave a witness mark on the primer, since the platforms do NOT have a firing pin rebound spring in the design.
It is not a primer selection/choice issue
ArmaLite AR-10's have a firing pin rebound spring incorporated in the design to prevent the issue.
I've run 10's of thousands of Federal 210's thru M1A's,M1Garands,AR chamberings,Bolt rifles shooting NRA OTC & LR Comps w/o a single primer issue.
