Ruger 10/22= .22lr with ten round rotary, semi auto, great gun

SKS=7.62x39mm Russian or Chinese made semiauto, rugged and hot shooting, looks wicked with a bayonet and folding stock

Ruger Mini-14=.223 semiauto, also really good looking with after market stuff

Ruger Mini 30=same as Mini 14, but chambered to a 7.62x39mm

Mini 14 is good varmint, 10/22 is a .22lr, but some use .22 for varmints a lot, the SKS and Mini 30 are a little heavy other than for coyote, but lots of people use them, including me, I have a paratrooper SKS. Gimme a day or two and your email and I'll show you what I'm talking about looking cool with after market stuff, folding stock, 30 round mag, 20 inch bayonet. It's wicked.
