Howdy all. I was wondering what size groups yall get at fifteen yards or 20 or so with your single sixes. Are older ones more accurate than newer ones? Reason I ask is I may buy one, but wanted to make sure of about how accurate they are. Ammo brand and range would be great details about your groups too. Pics are welcome! I know nothing about them so any info would be great. Thanks alot guys. Merry Christmas!
