A couple people had expressed interest in this topic, and I have a bit of extra time for a couple days, so here goes:
Bona fides: I am a former infantry NCO and sniper, hunter, competitive shooter, reloader, hobby gunsmith, sometimes firearms trainer and currently work in a gun shop, mostly on the paperwork/compliance side. Back in the day, was a qualified expert with every standard small arm in the US inventory circa 2003 (M2, 4, 9, 16, 19, 249, 240B, 21, 24, 82 etc.), and today hang around the 75th percentile of USPSA classifications. I've shot Cap-and-Ball, Trap and Sporting Clays badly; Bullseye and PRS somewhat better and IDPA/USPSA/UML/Two-gun with some local success. Been active in the 2A community since the mid-90s, got my first instructor cert in high school, and have held a CPL for almost twenty years now.
I certainly don't claim to be an expert in every aspect of firearms, there's huge areas that escape my knowledge base, but if you've got questions I'll do my best to answer.
Gun control proposals for feasibility
Some competition links (not my own) just for the interested.
