My contender wears a .357 barrel for cheap practice shooting, and a 7mmTCU for more serious work. Haven't taken a deer with it yet, but it certainly has the horsepower. The 7TCU is easy to load and easy shooting. IMHO, there are better cartridges in both the highish velocity bottleneck and slow and fat category availble. A 30-30 or .44 will get it done in their niches, but others will do it a tad better. I think a .35 Rem barrel would be the best of both worlds for hunting uses. You can run it like a .357 mag for practice, max for lighter critters with a heavy pistol bullet, or slow and heavy rifle loads for bigger critters. I own a .44 mag barrel, but haven't mounted it or acquired loading supplies. For sale if anyone's interested.
