Yea we went through a ton of the fundamentals, spent a good bit of time working on mag changes and everyone in the class(all 3 of us) found that even some of our higher end mags didn't seat well on a closed bolt and a full mag. Every PMAG, Troy mag, and D&H mag I brought had trouble I had to strip a few rounds out of a PMAG and Troy mag to get them to seat for the drill. Shot from multiple positions at 50yds, used a 9 hole board at 50, 100, and 150yds doing different drills. All in all a great class and I found a few things I need to work on and a few things to do to my rifle to make it work better in a non bench shooting scenario.
