I just did an initial OCW load development for my 6.5 Grendel. Found some awesome loads. But my upper had had a crack in it so I had to switch it out.
My question is, will I have to start my OCW test all over again? The barrel nut tension is a bit less then the previous upper receiver. The new upper receiver has a tighter fit for the barrel as well.. any help is appreciated.
I'm leaning towards doing an OCW all over again.
