Thinning down the heard is a very sad thing to do.............but if I were give those options I'd sell ALL of them except the 1903-A3. Take the money and buy a CZ 22 long rifle and put a good scope on it and then a Mossberg 590 with a bird barrel and a slug barrel.

A good 22, a 30-06 and a shotgun will cover ALL your needs for ever, and do everything there is ----------------------------- but will be far more boring then having a lot of guns to choose from.
