Because it helps harvest more does and more bucks would be passed on because they got missed. The buck to doe ratio in WI is way out of whack! Take a look at Iowa, shotgun only for the whole state and the ratio there is 2-1 maybe 3-1 in some areas. The ratio around us is probably 20-1 or worse. Bow hunting in Iowa is so nice, if you see 10 deer on a sit 6-7 of those deer are bucks and probably 2 of those are shooters (130 or better). The best thing WI DNR has done in the recent past was Earn-a-Buck then they took it away. Apparently the majority of hunters in WI want to see a lot of deer and shoot young bucks. Personally, I would rather shoot a bunch of does for meat in the freezer and put my buck tag on a Monster.
