Noveske 7PT Mod 0 chamber ammo

What ammo works best in Noveske 7PT Mod 0 match chamber?

I get good accuracy, sub-MOA with FGMM 69 gr 223 and poor accuracy with Black Hills blue box 223.

Maybe try 75gr TAP? Or a true 5.56mm load?

Just curious, but how old is the barrel?

Gen 1. 10 years old with low miles on it.

Very nice! Most barrels enjoy heavier bullet weights, but that doesn't mean 75 grain will always group better than 68 or 69.
