Okay. I just got off the phone with a very nice DNR officer. You are right. I am wrong. What I was saying was what they had intended, but not the way it turned out. Just like last year, when it was .243 and .30 caliber only. The legislators screwed it up. They should have it fixed for 2018. The officers will take this into consideration in the field if someone is ignorant of the change, not if they know about it. The 10 round thing also got screwed up. It was supposed to be High powered only, but is for all rifles. I asked him about 10 rounds of 44 mag in my rifle and 6 rounds of 44 mag in the revolver. He said he thought that was okay if the 10 rounds were "designated" for the rifle and 6 for the revolver.
So, before you go hunting with your 44 magnum (or 357, whatever) rifle and your handgun in the same caliber, take a sharpie and write "rifle" on the rounds you put in the rifle, and "handgun" on the rounds you put in your handgun and you'll be perfectly safe.
