Load development with suppressor or muzzle brake

[Paqueo]

If you developed a load with a suppressor or muzzle brake mounted and later use that same load with a muzzle brake or plain barrel did that load kept a similar group size at long distance? Not mentioning POI shift.

Mine has been pretty much the same. Not a noticeable difference anyway.

I measure my POI shift. Then I fail my regular dope I have with the brake and then subtract .3 mills and almost dead on.

I can make hits at 1k, take brake off, put suppressor on, subtract .3 mills, and get hits again.

My group size stays the same but POI moves up 2” without the suppressor.
