People tell me I should use a .22 rifle for squirrel hunting. I did that as a youth. The only way you're going to bag a squirrel with that firearm is if it is sitting still. Many times squirrels are fast moving and you only see a glimpse of them. This is especially true before the leaves drop. If you want to get your limit, or at least several for the table, what's wrong with a shotgun with No. 6 or No. 7 shot?
