I will likely be hiking and fishing in rattle snake county this summer in the John Day Middle Fork area. i was planning on carrying a Ruger Single Six with "shot shells". Does anybody have any idea of the effective range of the 22 mag shot shell? The other "bulky" alternative would be a Savage 22 mag/20 Guage or 20 guage pump. I am unable to find 38 or 357 shot shells. Any ideas on this circumstance. I always take with me my Airedale and Standard Schnauzer with me on my trips into the "woods" in Eastern Oregon, but this is a different country. I think I am wise to leave them home on this trip. Am I correct? Thanks for reading my post and your thoughts provided.
