The longer I am at this sport, the more I realize how much more enjoyable it is when the gun is set-up well for the application. I know, common sense....but the pragmatic/frugal half of my brain can't accept one gun=one task. The degree to which you chase that is up to you OP, but at least be honest with yourself about how you intend to use the gun and shop/set-up based on the top 1-2 things you plan on doing with it. Figure out why a varmint/heavy barrel is great for some things and terrible for others. Same for sporter-weight barrels like you'd find on a 457 or 452 "American". They all go bang, but you don't want to be lugging a varmint rifle through the woods hunting squirrels...but that's that's where an "American" would shine!
The advice you're getting re: caliber=perfect in my opinion. 22WMR and 17HMR are amazing and definitely worth considering if you plan on hunting (22WMR) or want to see a tight group @ 100 yards/hunt varmints. (17HMR) =that's how I see these calibers, and how I've used them. To me, especially these days with rising costs, it has to be a bigger job than a 22 for me to consider it. I do love the punch of 22WMR and have my eye out for a particular one of those too. lol
Last new scope I bought for a 22 was one of these;

There are 2-3 older models I'm always on the lookout for, but I mostly want at least 12X on the top end and either adjustable objective (AO) or side focus (SF) that will allow the scope to function best as close as 25 yards. Ideally, even less.
