RE: 30-30
No matter what make of gun you choose, the 30-30 cartridge is a super round for short range (inside 150 yards) deer killing.
Twenty five years ago, my Dad started me with a Marlin 336 30-30, and after many years of "magnumitis", I have returned to my roots. Last season, I killed 4 deer and 3 hogs with the new Hornady LeverEvolution ammo and am more impressed with the round than ever.
