Not to hijack, but it seems we are all wandering a bit so I beg a question if I may....
I was given an old Knickerbocker 12 double S x S by my mom's business partner. Guy bought it new when he was young, shot it just a few times and then put it in the closet. Well, he died at 92, gave it to me about 15 years ago. Now I have done some checking, I know they are pretty cheap, not worth much over 200 give or take so my thoughts are since it fits me nicely to use it as a shooter. I have not yet taken it to a gun smith to check for the safety of it (it has not be fired in over 70+ years and who knows if there are any issues).
My basic questions would be
1. Any precautions on shell types/speed/shot sizes or other issues that I should watch out for? I am talking probably about only shooting upland with this, probably lead, NOT DUCKS.
2. Any things I should do prior to shooting for the first time?
