Great thread, I agree with most above. It's your first muley hunt and you're doing it with stick and string. That makes any legal buck a trophy IMO.
I'm hunting in south-central NM this year which is the land of the 130 class muley but also where a lot of road hunters kill the first forkey they see....I'm not a fan as it really hits the herd hard taking out so many deer. Like I've seen with antler restrictions in Texas, I'd love to see NM make many of these marginal units 4x4 only. I believe you'd see a difference in 2-3 years and impactful change in 5-7.
I'm one to take what the mountain offers but don't need the meat bad enough to kill a forkey. Two years ago I passed on 3 120 class deer then didn't see anything other than forkeys on days 4 and 5. I went home to a big bowl of tag soup but happy to have had the opportunity and a great hunt. The year prior, I killed a 135ish 4x4.
