That may very well be the source of the confusion. However, those two courses are $125 a throw, and I doubt very much if anyone will take both courses when taking only one of them - literally - fits the bill.
The price is precisely the reason why I looked into the "22 hour" requirement. All I could find offered were those two NRA classes, one 10 hours, the other 12, and both $125 each. That seemed so steep a price that I decided to go through the actual legislation to see a) if that 22 hour requirement was true, and b) to see if there was a cheaper alternative (which there is).
The way the legislation is written, I could conceivably take the WI DNR Hunter Safety course given each fall at the local police station (which is free), satisfying the gun safety training requirement.
Having already participated in an NRA high power rifle course put on by Jim Owens, and having shot F-Class in an NRA sanctioned high power match, I might already have met the "training" requirements, according to the legislation. And, I plan on participating in an IDPA match, which does include range and gun safety lessons prior to the match, which also may meet the "training" requirements.
Even so, I'd opt for the NRA's Personal Protection course, even if it is $125, because it would cover more than just gun safety - it would cover the laws applicable to self defense and defense of others.
But if there was a waiting list for the NRA course, I'd try to get my CCW using my other "training" experiences, and take the NRA course at a later date.
