I am asking this question for a friend as I have no experience with microgroove type rifled barrels and he doesn't have internet access.
He has a Win 94AE in 44 Mag with microgroove type rifling in the barrel. He bought some factory 44 Mag ammo loaded with semi-wadcutter 240gn lead bullets and had terrible accuracy. The ammo in question was rated at around 1300fps out of a pistol barrel.
Using cast bullets what is the best way to load for this rifle in general?
Will cast bullets require that velocities be kept down to 44 Spec levels or can they be loaded to full 44 Mag levels?
Are there any major pitfalls to watch out for in loading cast bullets in this type rifling? Any comments or suggestions would be welcome.
Thank You.
