Kreiger barrel break in, is for their barrels be same for Bartlein and others. I'm not shooting factory barrels so who's ever barrel I want gunsmith to install I'll do break in.

I do it when getting scope on paper and I also load at range so get some fire formed cases for load testing, those first loads nothing wasted. If I get 5 cases fire form that 20/25rds and that about limit for 1st day.

I know only factory rifle I have is Rem 722, 222mag and I got that new and I think may of cleaned before firing.
