New thread to answer a question..

If (+) size rollers are to take up the play in a used bolt head are they OK to use in a brand new bolt head?
Just wondering....

I'm running +4 rollers in a brand new headbolt that i just purchased from Jorge. There shouldn't be a problem.

they also take up the extra space in a worn trunnion. They wont hurt anything to run them, but they may just raise the bolt gap too high in a rifle with new BH and trunnion.

Didn't get to run it much but there is just enough room in the new bolt head for +4 rollers. The old one you can rattle. Just like to double check with the group.
