Hello and welcome to the forum.

Ive had very good success with the Nicko Stirling Mountmaster 3-9x40 AO scope on my very powerful Hatsan.  It has no problem handling the recoil.

I have found hunting with that mag scope is fine. Wouldnt want to go to much higher as it makes it harder to locate your traget especially at night.

Gamos have very bad triggers and a lot of people dont like them. They are also not made very well and are considered entry level. But they will get the job done once you find a pellet it likes.

I wouldnt be looking at the most powerful thing on the planet because they shoot all over the place. A nice 800-900fps in .177 or 6- 700 od in .22 will make a nice easy to shot rifle.

I'm a more mature (which means near fossil stage) guy that's looking to continue hunting, but only with an air rifle.  I've previously, for well over 50 years, been a hunter and also in pest management and I'm looking to have some fun with air and also harvest small game for food gathering purposes.   I started with airguns as a 8 year old keeping seed eaters off our gardens with a Milbro 45, all 450 fps of it and then was gifted a BSA Meteor, far superior and way more distance and power.

I've kind of settled on the rifle, though there is room, given insight, to modify that however I've had Gamo before for vineyard pest control and, even though that was quite some time ago, their product has always been reliable and purposeful.   Tell me I'm wrong and why, please.

The real question is scope choice. I'm thinking 4-12 x mag and somewhere between 40 -50 ml objective lens sizes.

There are packages available from Gun City with their Ranger scope, but I'm a bit suss about their own branded stuff after several dealings over many years with them, and I'm thinking there maybe better options for the same or even a little more dollars?

Any ideas, please??
