Build a 22-250 or 22 Creedmoor with 7 twist barrel and he can shoot 75 grain and 88 grain ELDM's as far as he wants.
Planning to build/buy my dad a rifle for prairie dog hunting. He's expressed interest in a .22-250 but the buddy he will be hunting with shoots anywhere from 400 yards to 600 yards and in our state of South Dakota the wind always blows at least 10mph - 25mph it seems. I have wondered if a .22 bullet will be buffeted around by our wind too much to be an effective cartridge. Any suggestions for a better prairie dog cartridge or will a .22-250 suffice? Also, I feel I should note my dad has never owned a rifle before, only shotguns, and will be using factory ammunition. As tempting as a tighter-than-factory twist barrel and 75gr hand-loaded 22-250 sounds, I don't think that will be an option for factory loaded ammo that is readily found at Cabelas.
400-600yards in 10-25mph winds makes for a hell of a shot in my opinion...especially for a guy who has never owned a rifle before.
I would go with the 22-250 but try to set up closer shots...600 yards is not an easy shot...even with zero wind
My 2 cents anyway
And where can he buy factory ammo in 22-250 loaded with those bullets?
I'm familiar with the 5mm rem mag you mention...you're the first person I've heard personally testify to having used one. Cool. Irrelevant perhaps to the op's question but very cool nonetheless.I agree with your thoughts completely.. Although I might go even a bit farther and say use a .223 or .204; they are just more enjoyable to shoot for a day of gopher shooting.
For someone who has never owned a centerfire rifle. Shooting at prarie dogs at anything over 200 yards in the wind is going to be frustrated quickly. Don't think that is a novice's task.
We grew up trapping gophers at recess in country school and I find it hard to use more that a .17 hmr on them. Typically use .22, .17 m2, rem 5 mm or the .17hmr to spend hours erradicating gophers.. out to about 200+ yards.
Reserve the .17 rem, .204, .223, .220 swift and 6mm rem for wood chucks although I know a lot of guys like to use .22-250 and .243s on prarie dogs and shoot longer ranges. Seems like over kill when you grew up with them.

What projectile? Looks to have even opened up a fair bit.RPR 6.5 creed.....
