Dont discount the 25-06 for prarie dogs. It is a very flat shooting round, and a 75gr vmax or 85gr NBT are devastating. Maybe rechamber to a 25-06AI for another 100fps, which will put you at or over 4000 with those 75gr vmax if I remember correctly. Thats a ton of speed for that big a bullet. Sure would launch those dogs into the air!
