I tried it in .357 loaded with of 3.5 grains pushing a 158 GR LSWC and loved it. It runs about 780 fps at that loading and smooth as hell. Actually we have tire back stops at the range and I found a few bullets hardly deformed and just barely stuck in the tire.
I was looking for a super mild loading and it worked great.

It can be loaded to 4.2 @ 865. Not a screamer but fun to shoot!
