No arguments from me.
I had a 38" twist .50 cal. Bauska barrel that gave me MOA at 100 yards, using aperture sights fore and aft. The rifling was .008" and I mechanically fitted the 450gr. bullets (Lyman mould)by forcing them through a die I made from a piece of the barrel. Seems to me, the rifling was equal width, lands and grooves. After lubing, they were placed in a yellow Flambeau loading tray.
