Ken,
That is a very, very generous offer. I'm in the first steps of looking for an appropriate rifle for my son and will let you know when I think I have acquired something that might be work (He has been shooting an old, very heavy target rifle of mine off the bench, but really needs something closer to a sporter model.) Again, thank you for making such a generous offer. (Actually, it is too generous an offer - I will contact you offline to make it right when I have found the right gun.)
Remington- I shot up some odds and ends on opening day. I had a couple of black powder bismith #2s from the Metallic Cartrdige Company left over. After dropping two geese and scaring the beejesus out of my hunting partners, I then put in my GaugeMate inserts and shot some smokeless 12 gauge bismuth BB loads through the 10. When I replenish my supplies though, I'll be ordering the new 10 gauge ammunition from RST. RST just came out with some low pressure bismuth #2 loads for the 2 and 7/8" 10 gauge. A google search should turn up some sources.
