We used the 150 Clkt in our 30-30s on those small SE Tx deer. I've owned several Mod 336s in 30-30, and they just seem to like the 170 and even 190 (Hawks) even better. I actually like the Ackley version better, just looks neat to me. A 30-30 is an awesome hunting rifle! Many elk are still killed with them in the Youth hunt. I have a Pristine 1974 (yr my twin girls were born) Safe Queen being tweaked right now, reamed to the Ackley. Its a meat getting tool, aint it?
