Yes, you are correct, no FMJ allowed in MD for hunting.
Anyone have thoughts on 5.7 x 28 ( the blue tip sporter stuff) as a fox/coyote hunting round? With PS90. Seems ideal for fox without making a giant exit hole, and enough power to take down any coyote. It's got a good bit more oomph than a .22 mag, but not as heavy as .223. I got 100 rds off someone, and was thinking of taking the PS90 with me while trapping LOL. But I wouldn't want to mess up a good hide to see what it does for dispatching...if I can even catch a nice furred fox this season.
