They tried for decades to get hunters to shoot more does, and all the younger guys got into that damn QDMA crap and stopped shooting does all together. Now I understand guys wanting big bucks, but there will NEVER be a 160" class buck behind every tree in Michigan.
If you go back 25 -40yrs ago, starting on September 1st, you could buy a doe permit a day right through Jan 1st for private land. That's over 120 doe permits every individual hunting private property could buy. If you had 3 people hunting, that 360 tags available to just those 3 hunters. And the hunters still didn't harvest enough does.
I can tell you that in 20yrs we took 600 whitetail off the farm. We donated deer to every place that would take them, even many at GM. It got so we had to stop with the harvest as there was no place to give them away to.
Now back to the rest of the story............ Muzzleloader hunters numbers started to rapidly decline here in MI. That meant even less deer were being harvested. Then someone got the bright idea that if they allowed the use of straight wall cartridges, more would continue to hunt. Thus......... BANG! BANG! BANG! started during the muzzleloader season. The 450 Bushmaster was the original main firearm, then others followed. It worked to a degree, more hunters continued to hunt into the muzzleloader season using straight walls. Harvest numbers did increase, but not enough. CWD down below and bTB in the north............. those things also contributed.
For the past 5 or so years up here, because of the increasing number of deer and the decreasing number of hunters, they have sharpshooters killing deer RIGHT NOW! They will be out tonight with spotlights shooting ANY........ ANY ...... whitetail they see in a given area, including fawns with spots. They took 90 whitetail, does, bucks and fawns two summers ago in the area west of M-65 and south of M-32. The meat was processed and given to food banks in Detroit.
Its all about numbers in our state. RAPIDLY decreasing hunter numbers and increasing whitetail numbers.
Quite frankly, if someone knew the right person in the Natural Resources Commission, it would likely be very easy to get them to legalize SML.
