6 bra bore diameter

[savage204]

What bore diameter does everyone use 0.2360 or 0.2370 or does it matter? And how many grooves, ever tried 5r barrel? Thank you

 

[BRGUY]

I have always used .2350 and 3 or 4 groove.

I have used quite a few 5R barrels with excellent results.

Who makes .235 barrels

Brux 6mm’s can be tighter than .2360. I can’t tell a difference between .236 vs 237…in Krieger and Bartlein barrels.

237 AND 236 ARE BOTH USED. I THINK MAINLY A GUNS SMITH CHOICE. pick one and test some bullets in it. my dasher and ppc are all 237

I’ve shot .236” and .237”, 4 groove and 5R. All shot great. Flip a coin on all choices. They’re not nearly as important as you might think. Now twist rate, that’s important.
