Contact the match director, most will go out of their way to get a new shooter some assistance. Let him know soon as he may know of another shooter close to you that would help you get dope. Familiarize yourself with and practice the safety rules, sky loading and flagging are most common...
Call Mike with Elk Mountain Outfitters. I've hunted cows with him several times. One general elk hunt and am hopefully going again this year. Applied with 5 pts.
Mo Forbes was the outfitter best way to find him is on FB. The number I have for him is 307-631-4219. I hunted cows with him a few years ago. Located by Cheyene, got the leftover tags over the counter when we got there.
I know there are a couple different units in eastern Wyoming that always have leftover cow tags. I believe area 6 is one of them. Just about have to go with an outfitter because lack of public ground. That's the reason for the leftovers. Find Mo Forbes on Facebook and see if he can help you.
I use an Knives of Alaska caper. Small but efficient. Last year on our cow hunt, I quartered 2 cows same evening. Was losing the edge but got done. Have been using it for several years.
