I'm happy with the .22 caliber.
Since, while I am new to air guns (all disciplines), I do have a pretty good handle on the things mechanical.
I did a fair amount of reading in a couple of the different forums. Read a bunch of the "review" web sites on various guns. Watched a bunch of YouTube videos. Read the "descriptions" on various guns, went to the some of the guns, manufacturers web sites to see what each manufacturer had to say about their guns.
Did a LOT of soul searching to see...1. Do I need another expensive hobby ? 2. Do I want to get into something of which I know nothing, and will have to learn fast ? And 3. Do I need another expensive hobby (yeah see #1) ?
So...now I'm knee deep into another expensive hobby.
And yeah, still, the .22 is just fine for me. All I do is punch holes in paper, so I'm good.
