My thoughts:
Lined to .50 will increase the weight - reduce recoil yes, but you still have to hold it. There was a time for me when I couldn't hold up my 14 bore rifle, let
alone shoot it.
I was waiting for a shoulder operation for which I was told there was an 18 month wait to get on the Surgeon's "list". After 18 months waiting I entered their
office to speak to him or someone about "The List". I was told it would be a while longer as "The Dr. is VERY busy". I informed her to "tell him he's fired".
Long story shortened:
My cousin, a family Dr., said to not wait for the operation as it would not make me 100% anyway & to work at strengthening my shoulder. At that time, I "carried"
my right arm with my hand in my sweater's pocket. I took Rick's advice and I started a weight program and in 6-10 months I could hold and shoot that rifle. Since
then, I've never returned to the crippled state I was in & can still shoot any of my big bores, without the PAST shoulder protector I had to wear while doing the
later "training".
