I guess that is true more or less. Like I said when I was a kid I had a lot of fun plinking with a 22 off of my parents deck. I remember with two 25 round mags a 500 or 550 round pack would last me a week or two at most. Then when I was old enough to buy anything I could legally afford I bought a Russian SKS. At the time it was cool looking had a bigger round, made a bigger boom, and had some recoil to it. 20 years ago when I bought it I was 18 and the ammo was dirt cheap. I remember buying 1000 round pack for $100. I still have about 650 of those 1000.
I thought that rifle was super cool back then. Last time I went to range I actually took it with me. First time in a long time I shot about 10 rounds through it and put it away. Now I look at that rifle and wonder why people love them so much? It's a crude rifle that just feels so rough. I managed to put 10 rounds on paper with open sights at 100 yards. I think one round actually hit the 3 inch target on a piece of printer paper.
I shot much more rim fire accurately and had more fun doing it between my roughrider pistol teven my AR with the 22 LR conversion kit. I found the conversion kit in my long barrel AR with a wylde chamber sucks for accuracy but still comparable to the SKS using irons. I guess the kicker is the 22 costs a bit less even using 20 year old $.10 per round 7.62X39. Then when I come I don't have to sort the brass, prep it and reload it.
