when younger we did some very high volume culling and sure would have been nice to have those 25 round butler creek mags with the little red button on the spring to make feeding easier, less electrical tape on the finger/thumb, always tried to find the hollow-point ammo that would match rifle or most rifles, mil-dot scopes for sighter/correction holds (not wearing out turrets dialling), x-mas tree reticles would work great for it these days to get a little better wind holds, really liked the federal blue box hollow-points I think they still make something similar, one bolt action I had loved the Remington sub-sonics and was deadly set up (ruger 77/22) but all the bolt actions like cz, savage, and even the ruger 77/22 eventually painful to keep loading and firing after long day of smashing gophers and deep into 2nd brick
currently I would be tempted by a savage a22 or ruger 10/22 with those 25 round mags with the easier loading, should be able to find acceptable accuracy with those two with some of the hollow-points around today, if they make bolt actions that take those magazine then that would be a great choice also! even more likely to get the accuracy needed, lightweight sporter barrels, Harris long swivel bipod, padded butt seat strapped around waist, fanny pack with gopher whistle and at least a brick of rounds, and a sombrero...set for an entire morning, lunch break, another brick of ammo into the fanny pack and do it again
yeah I see savage has the b22 bolt action that would take those butler creek 25 round mags, I'd just research any accuracy differences between the a22 and b22 and if the a22 can shoot with the b22 then get the semi-auto and two of those 25 round mags, they stick together and have the easy button for reloading, you can then reload 50 at a time, save the fingers, stay in the scope for sighter/correction shooting, good reticle choice on scope, keep it light barrel models for all day handling, easy to come up with the best high volume gopher set up these days, the sore fingers with little 10 round steel magazines etc. was the number one hassle back when
