Even though we've never done one of these and don't know quite what to expect (especially at the NRA range!!) we're willing to give it a try!
Our goal is to finish the course of fire without getting yelled at by the RSO for safety violations!!

Not that we're unsafe....you can never be too safe! But it never hurts to practice! My family have all shot the Thompson alot AND ARE VERY SAFE, BUT have never shot in any type of competitive setting, OR at an indoor range! (I'll probably tag along with the RSO when each of them shoot, just in case!).
Gun shot great with only one stovepipe in 600 rounds (New Wolf polymer coated ammo) although we have 1000 rounds of S&B and 200 rounds of Winchester that we are bringing to the Shoot, per Tracie's "no Wolf" request.
This will go down as one of our cooler vacations and we're looking forward to meeting a bunch of you folks!!
Eagerly awaiting.........
