Your CCW permit will meet the training/experience requirement. Next you need to belong to an affiliated organization. NRA doesn't qualify as an affiliated organization--this really sunrises me. There are a couple of organizations you can join online at very reasonable cost to meet this requirement. One is the Garand Collectors Association and the other is the M-1 Collectors Club. I joined both but have only maintained my membership in GCA. It is more expensive but you get a nice glossy magazine from them. It's a pretty good deal for $25. I think the other was only $14.
When I bought my rifle I sent a copy of my GCA card, my CCW permit and my ID page from my passport along with the notarized page. I'm considering buying another rifle this year and you don't have to get the form notarized again for three years. It was a lot easier than it used to be just a few years ago where you had to send in fingerprint cards.
Thank you for that info. Very reasonable price for the organizations you provided.
I hope I am able to get one as nice as yours!
