I have a many different firearms, but only a few that end up on the hunt regularly.
They are all used on different species though.
1. My Ruger Frontier .308 Winchester,With Leupold VX 2 3x9x40 Scope, its used for Deer and Wild Hog.
2. My Mossberg 835 Ulti Mag Shotgun, Its used for Various Critters, and Birds, including Turkey.
3. My Wichester Model 270 Pump .22LR Rifle with Weaver 4x Marksman Scope. It is used almost entirely for Coon Hunting with Hounds, its has reflective tape on the stock to help me aviod loosing it.
4. Stainless Steel Ruger Single Six Revolver, it has a 6.5" barrel, and is chambered for .22 Magnum I carry this while Coon Hunting, when I dont have my Rifle with me, I keep ear plugs in my shirt pocket, and have shot a few Coons out of trees with it. Also killed a Hog with it one night in a thicket.
Those are pretty much the tools that I use for my various adventures, the rest of my guns are just for looking at and shooting at paper ocasionally.
