ScoutV2. ,Re 357RemMax bbl length, unless you're heart set on 10.5 in.s please consider 12in.s. I've posted here & there before on the R Max & bbl length. I've had or shot most factory bbls & lots of custom ones. I really think 12in.s gives the best balance of velocity & handiness. I have several Contenders as well as Encores. All of the Encore tubes (so far) have 15in tubes
But sometime soon there will be a 12in 454 Casual added. I passed on a custom 12in 357RMax at a local show some time back & have regretted it from the time I drove home!! AND I had two R Max already! Whatever you choose, just feed it some LilGun ,296 ,or 1680 w/any 140(slowed down a little) 158,or 180 gr bullet w/small rifle primers & you'll be happy. Have fun, load safe & shoot straight!
