I hear ya gunner, but this isn't a 760, it's a Savage 170 tube fed trombone. Not sure they're all too rare, they were kind of a budget gun in their day. It's a nice handy shell shucker as is, probably why I haven't sent it in yet.
Neat rifle though. They shoot well?
I haven't sat down and tried to squeeze groups out of it. I did run a box of WW 150gr Deer Season through it checking sights and function at about 50yds. It fed, fired and ejected perfectly and the cheapo scope in Weaver roll off mounts, as well as the irons, were still spot on. It shot as well as I held sitting with my back against a tree, easily "minute of deer heart".
