I would recommend the .308 bull barrel. I have mine sighted in at 200 yds but it will do whatever you want. It might be a little overkill for groundhogs but I doubt you are shooting them for the meat.

thats the only post that makes any since in this entire thread .
make up your mind man , first you say you want to shoot long range then you say you want a 22 hornet??? and what retarded shooting god told you that a 1-12 twist 223 can't shoot past 200 yards??? and why are you afraid of burning powder and shooting jacketed bullets???
if you want to get in to the long range game , as your first post suggest then you need to start doing a lot of reading and if i were you i would buy a bull barrel 308 because it will have plenty of ass to buck the wind out to 500 and beyond and your not going to burn the barrel out trying to learn how to shoot and fine tune you rifle. the 240 weatherby , the 243 , the 22-250, they all burn barrels out to fast for a beginner to learn on, and the 270 win , hell no you'll find match ammo and even if you hand load match bullet are few and far between
you will also have to have a range finder , its really then only "doodad and thingamajigg "needed for shooting at mid to close range .
oh ya and this rummer about high velocity being needed for long range shooting is bull crap , try to keep it above 2500 and you'll be set. get your gun shooting 1/2 to 1/4 minute groups (5 shot) and you can just adjust for drop. a slow bullet going where it told is a lot better then a fast bullet hitting where ever it wants.
stay away from wildcats . you'll be spending too much money that you could be putting into you glass.
think of it this way :
your barrel is your tires, they brake in and ware out quickly
your round is your engine , it has to be running good and well tuned if it can be faster and still run good , all is well
your receiver is your transmissions , if its not running smooth or the crap don't fit right your not going anywhere.
your scope is your windshield , if its not clear and stays clear your not going to make it 15 feet. this is not a place to cut corners
your trigger/shooter is the driver, if the nut job behind the wheel can't drive it don't matter if he's driving a Ferrari he's not going to win any races , buy a old car and take it to the parking lot and start at begging (buy a ruger 10/22)
and remember stalking crap is a thing of the past if you can see it you can hit it no need to brake sweat walking closer.
