.570 dia RB. What for?

[Okie Hog]

My .58 is a Mr. Hoyt re-bore with rounded grooves and 1/66" twist rate. The rifle is very accurate with 100 grains of Shooters World 3F powder.

I use .570's in my Carolina gun.

My 58 is a Robert hoyt rebore. I highly recommend him for your conversion.

I have a boring bench and will be rifling it at gunmakers hall at the fall shoot it'll have gain twist rifling

I will ! I may make it into a 56 cal. If the bore cleans up if not I'll go to a 58
