I've been using a Ruger #1 in .270 cal. for many years on whitetail deer. We rarely get a second shot on them anyway in the thick woodlands of the South, so the one shot really doesn't create any handicap at all. If I were hunting Griz, I'd probably feel differently...Geo
Geo, it's nice to see someone other than me that uses a Ruger single shot. I use a Ruger #3 carbine in 45/70 with open sights. I initially bought it for a bear hunt in Canada back in 1978. Some people thought I was nuts for using it on that hunt. I guess it all boiled down to confidence in my carbine and shooting ability with it. It has since become my first choice for deer hunting up here. Should I ever go bear hunting again it will definately go with me.
