My Dad used to use a 14" 30-30. We never really did find a good whitetail load for it to consistantly perform well with. That's why we traded it off. 125 grn jacketed hollowpoint was the best.

The cartridge is NOT very efficient. Shake a live round and you can hear the powder shaking back and forth. In a 14" barrel the velocity isn't what it should be for factory ammo to perform to it's full potential since it is made for a rifle.

Ours was always very accurate, we just never were satisfied with the down range effectivness on a Whitetail. (just my 2 cents)

I hope you have better luck with it. and if you don't, as mentioned above, have it modified to a 30-30 AI.
