I enjoy the guns I have, but there are a few more I'd be interested in acquiring someday.
I'd kind of like a full-sized .357 revolver someday, just for fun. I shot a long-barreled S&W 686 when I was in college, and it was neat.
An AR-10 in .243 or 7mm-08, for a combination deer-hunting and longish-range-paper-punching rifle. I really like the Remington R25 Gen II, but might have to settle for getting a stripped lower and building something as finances permit.
A Savage 110/111, Tikka, or Browning X-bolt with a nice scope on it. I passed up a used Winchester Model 70 in .30-06 a couple years ago for $450 that I sort of regret letting get away.
Another Romanian SAR-1; I had to sell mine a few years ago and miss shooting it.
I don't own any Title 2 items, but I saw a review of a neat integrally suppressed .22LR built on a Ruger frame a while back that looked like a really fun plinker.
Maybe a repeating shotgun of some flavor, for fun.
Finally, after shooting a mentor's handloads a couple of times and being surprised by the precision vs. commercial ammo, I think I'd like to get into limited reloading of rifle rounds, for precision rather than for high volume. I have never before or since shot a 1" group at 200 yards, and was floored...want more of that!
