Ok, 2 years ago in Oct. my wife had made arrangements to go to the little town where we have our summer cabin for her birthday. I planned on taking a day and calling coyotes. Looking at the regulations, I was lost, so I called the local office in Gunnison. The gal I talked to didn't have a clue, she told me I couldnt hunt coyotes as there was an elk season going on that weekend. I then called the main office in Denver. Got to a really good guy.
Anyway, in one part of the regulations, it said you could only have a 5 round magazine. I cant remember what other questions I had, but the guy said "Wow, I see why you were having trouble, these are hard to read". Anyway, for furbearers you can use any quantity magazine, for big game (mountain lion) you can only use a 5 round.
