Interesting thread, I'm in a similar boat myself.
I just picked up a CVA Scout pistol with a 14" .357 Magnum barrel, which also came with a new PTG .357 Maximum reamer and Max brass/ammo. The CVA is brand new, and I haven't checked to see how long the chamber is. My debate is whether or not to ream it out to Max, but I do want to get some .360 DW brass and see if it will chamber. Ideally, I would like to shoot 180gr XTPs to 200gr hardcast lead bullets.
