If you want an investment, buy ammo and sell right before the election.
If you want a good .22 centerfire, at bargain basement price, a 722 in .222 would be the ticket.
It even eats less than a .223.
The only downside is that they did not use a very fast twist, IIRC- no heavy bullets ..... but if you can' kill a varmit with 55gr bullets..... I dunno ......
Also, the stocks on those will require a comb raising kit if you want to put very big glass on it, more than likely.
