Since all this craziness started with Covid and the savages burning and looting. I have been shooting a lot of 22's (handguns) since the 9mm shortage and absurd price increases. My centerfire handguns spend a lot more time at home and don't get shot as often. I recently decided to take my two nines to the range and I was completely blown away by the improvement of my groups. I can only attribute that to the amount of 22's I've been shooting. I've always read that practicing with 22's doesn't help improve your centerfire performance. Well I have to beg to differ, since my centerfire performance has improved 10 fold. I can now effortlessly shoot quarter sized groups at 18yrds. My norm was 2 and a half inch at that distance.
