Nice goat! I took my then eight year old daughter on an antelope hunt in Wyoming last year. I didn't kill a big buck, but it was the best trophy I ever killed when she said it was worth the drive from New Mexico to Wyoming because she got to spend time with Daddy!
Have you ever thought about a Model 70 Featherweight or Model 700 Mountain Rifle in 280 Rem? I have a buddy who shoots a Model 70 Featherweight in 280 Rem using hand loaded 160 Partitions and he has had great success on everything from speed goats to bull elk over the last 20 years with this combo.
