Re: 30 carbine
The only hundred grain 30 caliber bullet that I'm aware of is the Speer "Plinker". Not a good hunting round. The standard bullet for a 30 carbine is 110. 110 soft points and hollow points are available from several manufacturers.
Many people say it is too small for deer. And many deer are killed with it every year. The normal deer, here in Florida, dress about 40 pounds, with a live weight of maybe 75 or 80. I think it's fine for them. 300 pound mule deer, in Utah, at a range of 500 yards - not so good.
Michigan deer? They're kinda big, I understand. I think I'd want a bigger gun.
