I think I'd paint the one you've got and then get a real rifle....the Handi .45-70
Perhaps I'm wrong, but I believe you have Red Deer that would be worthy of it. I'm a predjudiced Yankee on Michigan's Upper Peninsula, and the .45-70 works well for about everything here....squirrels to bear. It is a lot of fun to shoot and find loads for everything from rodents to elephants.
I have stainless in a Handi 30-06 and a .50 Huntsman. They're a brushed finish and don't really reflect that badly. The last deer I took with the Huntsman, not only didn't see the rifle, but he never heard it go off.
Good hunting and shoot, mate
