After much research the JP muzzle brake was decided on as it does not push the barrel in any direction other than forward. Once zero was found ( see target) and a load worked out the brake has never caused any problems with long range accuracy.
Where on the muzzle axis vertical whip angle did bullets leave before gas ejection pushes the brake and barrel forward compared to without the brake?

That brake changes the barrel's vibration frequencies and angles at the muzzle as well as its node places (zero vibration points at different places) while bullets go through it. It acts exactly like a tuning weight.
