I want to finger tip crawl up to them and blast them with my P7.
I guess this would be my varmint gun by default...

With optimal 70gr ballistic tip match grade ammo and proper magnified optics i bet it would do at least 250 meters vs small critters. Of course i own neither optimal 70gr ballistic tip match grade ammo nor magnified optics.
But if i did...
101rds of prairie dog blasting fun.
