Re: 6mm BR by MCR
Larry trued my action also, and the threads are .008-.010 over, all 4 barrels that I had him make for it fit and function perfect, I know that some factory produced barrel will not fit correct.
I started with a 112BTS (for those who don't know, it's a Long Action Single Shot late 90's production Targt Rifle, first version Target/Competition action) that he also has fit 3 bolts for, 1-Mag. (Factory .300 Win. Mag.)), 1-med(..308 case Family) and 1-Small for .223 Rem.
I've won local Club Titles, a State Championship and set a National Record with it, think he knows his stuff.
