I cannot imagine finally drawing a coveted sheep tag, only to bring along one of the biggest piles of garbage guns ever built.
the hardest part of a sheep hunt is enough cash and drawing a sheep tag ...
I've killed 4 of my own rams: 3 Montana bighorns and a Canadian Dall. All one shot kills with my Interarms Mauser Mark X .257 Ackley and 117 grain Sierra GameKing bullets. It's more about where you hit them than what you hit them with.
Each of my Montana bighorns cost me a $25 resident tag and a tank of gas.
