A few .22 lr questions?

I have had a 10/22 for about 15 years and I am 28. I now have 5 guns in .22 LR and I love every one of them. I wouldn't say it is a must, but it sure is much cheaper to shoot then most other guns. I have the 10/22 and a Mossberg Tactical Plinkster and the 10/22 is 10 times better.
