"However, I am having shoulder replacement surgery in 2 weeks, so I wonder if I will still be able to use this rifle in the future. The recoil is not horrendous, but it is certainly not a .243."

I had rotator cuff surgery two years ago and have worried about the same.... Have not shot the .405 since then but plan to this summer...
