I think for starters, maybe a short blurb on your own history with firearms and then maybe listing what you have or have had the chance to shoot
Myself, I spent 6 years in the USMC. Shot just about everything in the arsenal short of a main tank gun. Hunted when I was younger and now I'm into the history and collecting of WWI-WWII military rifles (with my brother. We mostly share our collection) Currently have:
