Sounds like you've made up your mind but here's my 2c as a new shooter (1.5 yrs) who hunts and has been moving up the recoil charts myself.
- Started with .22 (like you have) - great starting point, cheap plinking. We love our .22s, and I love not going broke every time we go target shoot.
- Got a .243 - 7-9lb recoil, seemed like a lot at first. Flat shooting, good for deer. But expensive if you want to target shoot.
- Got a 7.62x39 - similar recoil to the 243. Was just going to be a toy gun, but after finding the ballistics are very similar to a 30-30 I now have 3x 7.62x39, one each for my 2 boys and 1 for me. They are replacing the .243 as our deer hunting guns this fall, and the kids can target shoot surplus ammo all summer long without breaking the bank.
- Next got a 30-06 - 15 lb recoil. Was going for .308, but a steal of a deal came up on a 30-06. It will be my moose/ elk/ bigger game rifle this year.
Lastly I will say - buy whatever you want, try it out, if you don't love it, sell it. I've found it very easy to sell firearms, especially now that prices have been going up. I have a buddy who reloads, good if you know for sure you will love it, but for me I just buy my factory loads and surplus as I'm not convinced I will be committed to reloading.
And I have kids and just don't have that kind of time. Seems great if you're retired.
PS - how the hell did I end up with 12 guns a year after my PAL? wtf?
