Breaking my cherry here in this forum, but for what it's worth a fellow will get a lot of benefit from rollin' his own with leverguns, regardless of maker. Finding factory fodder that works is never a bad thing, but probability is that hand loads will get to the point quicker. Whole bunch of variables involved with lever guns that factory production ammo can't/won't address on a case by case basis.
Sometimes lead is your friend, sometimes not. Have 3 ratchet slammers, they all run well. One has exhibited worthy performance with factory ammo.
A Marlin 94 .25-20 Win, first day at the 50 yd line:
Those particular bullets were a fairly soft alloy of 10 BHN hardness and based on load info somewhere in the range of 1300-1400 fps. The gun uses a Lyman tang sight.
If one is inclined, a little juggling with COAL is usually doable and the relationship between bullet form and chamber dims has a lot of play when shooting cast bullets.
