.270 is a great goat cartridge.I use Barnes MRX myself but Nosler Accubondor Partition, ,Hornady Interlock, or SST's, Sierra Gameking offer a great bullets that will get the job done.. When it comes to goat,it ain't about the caliber, it's all about mind over matter..Not only do you have to be in great great shape, you have to be mentally
be prepared as well.. It doesn't matter how prepared you are, when goat hunting, if your mind fails you fail and not only do you fail, you will never Ever!! attempt it again.. It is the hardest hunt you will ever go through it will put you through the ringer, both mentally and physically.. .Good Luck..If you can do this you can do anything you set your mind, body through, reguardless of weather conditions, hieghts,
and shear dropoffs..
