Let me start by saying I have owned "2", 22 rifles over the past 50 years. I sold the last one, a Rugger 10/22, after letting it sit without use for decades.
I have also owned small Beretta and colt 22 pistols along with a NA 22 mini-mag with LR and Mag cylinders. I also never used it so I sold it also.
Now taking general inventory, I have pistols, an AR, and a 12 gauge, pump, "none of the long guns ever get used for lack of a place to shoot them".
Do I need to rethink this and get a 22 Ruger or perhaps the over molded, or heavy barrel, little rifle . Just to have one with a few thousand rounds, for emergency's, or leave it alone, being that I probably won't shoot it much unless I start shooting the pistol in some sort of competition.
I know that "most folks" say you have to have a 22, seems like a reasonable question I have asked myself with no answer. I have been shooting more lately, after a long break other than my carry, but am limited to a 25 yard indoor range. Is it only the survivalists that theorize having one for emergency's is a wise cost effective tool?
I assume that it would be a cheap way to get small game in a real crisis.
