Thank you for your service to our country. It is something to be proud of.
That does not make you an expert on guns of all types, especially .22LR.
Since about 9 I began carrying and using a rifle and shotgun. I went hunting with my Father and Brothers a few years before that. I have spent nearly my entire life in rural areas hunting, target shooting, plinking, killing farm animals, killing varmints etc.
I will admit that of the several hundred guns I have owned over the years, a Siamese Mauser in 45-70 was probably the most powerful tho the 7mm Remington mag probably had more energy. I have seen what the .22LR can do and it can do a lot. IT is not forgiving of bad shot placement.
I am a certified firearms and hunter safety instructor, at least I was until I let my certificates expire. I taught skeet at the University of Southern Mississippi for two years. There are a lot of people who know guns better than me but percentage wise it is not many.
