F-TR obssessed shooting junkie
I wonder if they'll allow a NM M1A with optics into this class.

Don't think so...
From the rules above: Any semi-automatic rifle constructed on an “AR-Style Platform”

If it allowed m14 types id be in.
Yes, it will stay above Mach 1 *if* muzzle velocity is above 3000 under most reasonable conditions (sea level, above 50 F). At 20 F one would have to make 3070 or so.Will a 55gr FMJ stay supersonic at 600 yards out of 16" AR? I have seen some AR's at 600 yd matches that didn't stay supersonic. Not sure what they were shooting. They might need to think about a minimum requirement for ammunition.

To answer your question, I think loads would have to be right near max for 223 rem with the 55 fmj.
My question is whether that is something that we must regulate. Service rifle guys with M1A's regularly hit at subsonic speeds at long range without too many deleterious effects.
We could also be kind to new shooters and introduce the class with a 300 yard match and work our way out while teaching our new friends what it takes to get on and stay on paper at longer ranges.
