I own, shoot and hunt with both 30-30 and .35 Rem. lever action rifles. I load all of my ammo, using either jacketed or cast lead alloy bullets that I pour myself. I prefer the .35 Rem. and its larger diameter, larger flat-nose bullet for deer. But, if you will be relying on purchasing your ammo; I would strongly recommend that you go with the 30-30. -Ed
