Welcome!
If you're happy hunting small game, go with a .177 or .22 caliber. Bear in mind the larger caliber (.30 and up) guns use LOTS of air which makes your fill source very important. Do your research on pumps, tanks and compressors. If you don't plan to spend a lot of time at the bench target shooting you can get by using a pump. You won't shoot down to minimum pressure, just take your few sighting shots and the handful of shots on game in a typical hunt, then top off with the pump. If you shoot a lot, a tank or compressor will be a necessity. If you live where there are a lot of dive shops they may be a source for tank fills. Scuba tanks are OK for low pressure fill guns like the Beeman Chief or similar, but if you're shooting a PCP with a 3300 psi or higher working pressure a 4500 psi carbon fiber SCBA tank AND a way or place to get it filled will be necessary.
There are lots of options out there, bear in mind the more entry level guns often require some tweaking to shoot well. Ammo is also critical, most guns will group best with a particular brand and weigh pellet.
Good luck on the journey down the rabbit hole, and remember to enjoy the ride!
A couple suggestions for a rifle-(just my opinion and worth what you paid for it, LOL!)
The Daystate Huntsman- light, accurate out of the box, easy to shoulder and carry. Slight downside-OEM magazines are expensive, but aftermarket options exist.
View attachment 330044 The Benjamin Marauder-a bit on the heavy side, but a proven dependable rifle with great customer support from an American company, tons of aftermarket modifications available, extra magazines are inexpensive and readily available.
