Just to clarify, they specified 6 in a semi-auto - in response to centerfire, that would include 1 in the chamber.
I was asking when I wanted to take the AR small game hunting and their answer was 6 - couldn't find it in the regs for small game.
The Big Game regs do say:
c. If semiautomatic, they can hold max. of 6 rounds in the magazine and
chamber combined.

I wanted to take my kids hunting with the .22 hence their 2nd part answer was stated as referring to .22 rimfire magazine capacity to manufacturer's magazine. As far as making your own .22 rimfire rifles- I did not request that information and they didn't address it.

But I will go by what was written by DOW and be on the conservative stated side and not worry about a game warden, just wanted to throw out an actual written statement. If any want to call what the DOW wrote as wrong information, please throw me something written somewhere so I can know it's wrong as well.
Or if enough people ask the main office, maybe they will clarify it in the regulations...
