Thinking about an M&P 10 "just because".
Quite a few years' loading for and shooting various ARs, Garands, and M14s/M1As makes me wonder just what people are stuffing in these rifles. My experience with the foregoing was that given decent in-spec ammo and maintenance, reliability was outstanding.
My M1A always ran just fine with 41.0 gr. 4895 and the M80 FMJ 147gr. or the 168gr. SMKs.
If your M1A is a .308, you can expect about the same performance with the M&P10 from what I've seen with mine. The recoil maybe a bit less but all I've ever shot out of an M1 Garand is .30-06 blanks, so no real basis for comparison for me. The M&P is a bit lighter and about the same length as an M14.
