You should be fine. But... a new bolt could have a slightly different head space than the one you currently have, causing a slight change in pressure. So your load could run slightly slower or faster. This could change up the POI. But if it's the same ammo and the bolt has the same head space, you should be fine.
Thanx for input will probably replace the extractor and keep it for a spare. I work out of state and wont get back into town until night before supposed to go hog hunting, at this point replacing the bcg is easiest option. The extractor that broke only had approx. 60-70 rounds on it. Shooting Hornady Black 120 grain

I have switched BCG from my 2of my AR's in 223 and my 300 blk out, and I don't notice a difference. But I'm fine with moa performance in them, and often confirm my zero again when I switch back or make changes.
