Rifling depth is .016" per side for all .45, .50 & .54 caliber
barrels .012" deep per side. All barrels are round bottom (radius
groove) rifling. This is an old form of rifling that because of the lack
of corners in the grooves is much easier to clean and also allows the
patch to seal better. All rifling is six grooves.
