Thanks for all the comments, guys. This is the time of year to get things done at the gunsmith, so, I think I'll take it in and have an R3/Limbsaver installed.

Skeeter: You're absolutely right about psychology and the mind having a powerful effect. One of the lessons we tried to take from our martial arts classes, particularly applicable to breaking boards and bricks. For some reason, I could never convince myself that I could do a reverse punch through 2 1X12" pine boards. Bloodied my knuckles on them, but couldn't break them simply because I "knew" I couldn't... But, no problem with doing a hammer fist through a 2" brick. Go figure. I'll work my way up... 140 gr. Managed Recoil, 140 gr. Magnums, maybe if I can get through a box of 160 gr. Magnums without flinching, I'll treat myself to an elk hunt...
