Dave to be honest, if someone were to look down the bore of that old Knight on a used rack they would put it right back down - me included. But the funny thing is that I bought it on an online auction for $50. When I got it the first 2" of the bore was a mess (and still is). I wouldn't call it rust, but there are 3 areas about 3/8" or so in diameter where the bore is corroded from something. But the rest of the bore is perfect. I have the 'bad' area polish so that you can't feel any roughness during loading and cleaning. I have it topped with a 1.75 - 4X Bushness shotgun scope. This rifle has already shot 300 gr Shockwaves into less than 1" at 100 yds.
So I guess all in all, the rifle was worth the $50.
Now if you want some of these bullets PM me your address and I will get them out to you.
