That sounds like that sucks,, I was a tree surgeon for 16 years, and my hands and elbows are shot, then I started plumbing in 99, and they got no better, after a series of 8 Hydracortisone injections in each Ulnar nerve I have severe pain daily in my joints..... But you have to maintain and persevere.
Ps nurses dont like the smell of Balistol
Hey also there is a lot of tinkering you can do with that ole "flat top" to really get her shooting good, what's the bore look like?
