I don't have a .357, but rather a .44, and it's a 2 to 2.5" gun at 100 yards with some of the various 300 grain bullets I've tried.

I recently replaced the factory trigger with a Volquartsen. It's a big improvement. I also free-floated the barrel at the same time, and now groups have a much more "round" appearance to them, probably due to the better trigger.

As far as hunting, for the terrain I hunt, it's great. Light and accurate enough for the ranges I typically shoot deer at.

I have a Leupold VX-2 1-4X20 on mine.
