Groove/bore size Q

[19818119]

Gents,

I have to choose either a 4 or 5R groove as well as either a .236 or .237 bore for a .243 win bbl Bartlein 1/7.5 twist bbl

Which and why?

Thanks again.

Rath

You won’t be able to tell the difference. All of the 6mm barrels I've ordered have been 4 groove .237"/.243".

I had a discussion with Frank Green at Bartlien before, he's shot them all and as per usual with all of us, they all out shot him.

It's going to be hard to go wrong with a 4 groove .237"/.243" 1-7.5" twist barrel if 115's are going to be the diet.
