i had a few questions about this ammo. i might be picking up a marlin 336 in .30-30, and i was wondering if this ammo would perform well in this rifle. i know marlin made another levergun just for this ammo that has a different rate of twist. however, hornady says on the pistol bullets its ammo increases performance in the shorter barrels. has anyone used this ammo in a 'regular' rifle? any info would help, thanks.
