if you run over your & bend it while its off
the accuracy will change
just kiddin....
if the barrel was previuosly accurate on said receiver & you mark the barrel so ya get it right back to same headspacing so ya dont have to set up headspacing every time
it should shoot exactly the same as it did last time on that reciever with that headspacing
I have a 06-300wm I switch barrels on -both barrels markings recorded for next time'
I dont know for sure -but I feel like you could change a barrel to a different reciever & the accuacy would stay- move with the barrel
I may try it just to see -
