Thinking about using my birthday/Christmas budget to get my first NFA item and the plan is to grab a Shockwave to Form 1 from the local pusher. My use case is strictly for fun and hopefully a class or two. No plans for HD, duty use, etc.
I keep more 12 on hand than 20 but it looks like the cost per round is pretty close. I believe the only 20ga Flite Control loads are hunting loads. For a fun gun, is it really that big of a deal? 20 is definitely easier on the shoulder and for new shooters/smaller shooters (thinking about the grandkids if they decide to start shooting).
Are there any other compelling reasons to choose 12 over 20 in this case?
