Cant help with any AR comp data, most accurate load so far fo me is 24.2 varget at 2.255 coal out of a 20\” barrel.
Wish they could get that dang sawdust out of hollow point, I think this is a pretty good overall bullet though. I ussually do .1 grn increments and watch the groups open and close, not alot you can do with length in an AR….good luck
