yeah I hunted them about 5yrs ago and it was a blast!!! I got mine with a .243 remington. my shot was only about 125yrds... then again I shot him while I was eating lunch at camp!!!
other than that... my other two hunting companions shot their's with .270s at about 150yrds and that is PLENTY of fire power for those goats. they are not as hard to bring down as a whitetail. but sight in your rifle!!! and know how much that bullet is going to drop....
