@techriot .308 Winchester?
@techriot I started out with .30-06 and stayed with it until I got old. .308 is a bit easier on me. .308 offers a multitude of choices too.
@techriot I don't shoot much anymore, but .22 is a fun round. Also a variety of ammo and geegaws for fun.
@techriot I picked up my first and only airgun a couple of years ago. It's a Umarex arrow shooting rifle that runs on Co2. I don't know if airbow is the correct name but it's fun to shoot. I bought it for stealth, but unfortunately it's about as loud as a twenty-two.
