I have a 10" barrel. Looking for a bullet to hunt deer with. Not sure if a rifle bullet will work because of the slow velocity. Thinking of a varmint or hollow point. I remember there used to be bullets for single shot handguns, not sure if they are still being produced.
I'm not aware of any of the SSP pistol bullets still in production. Could be though.
I would look at the 125 (hollow?) flat point from Sierra and 130 gran flat point from Speer ... they are purpose-built for .30-30. Consider the Speer 125 grain TNT and 130 grain JHP as candidates .. probably need some expansion testing. I would consider the 110 grain VMAX with the same testing first. 125 grain Nosler ballistic tip and Accubond have a good reputation in .30-30 handguns. I would consider 150 grain flat points as well. 150 grain spire points don't behave reliably/predictably at .30-30 velocity even in a rifle. We had a couple of Savage bolt actions and the 150 Sierra and 150 hornady pointy-point bullets completely failed to expand even at hair burning distances more often than not. Mom plugged a big cow in the shoulder and they found the bullet under the hide in the opposite ham unexpanded.
