Re: BSA Sporter for sale/sold

My 2-groove (new barrel) #4 has a groove to groove of .315".
I rechambered it for the .312 Express (see Ken Water's article), and it does 2,960fps with 174gr. Hornady bullet marked .312", using Reloader #19. It has put 3 of those into 1 1/2" at 100 meters off the bags when testing.

It would not shoot 220gr. .308's, although it tried. They didn't keyhole, just shot an open 6" group.
