And I'm only 29.
First time I pulled the trigger on a firearm (had been shooting BB guns since I could hold them up) I think I was six or seven. Since then I've done all sorts of things. Shot competitive three and four position .22 Olympic rifle, and did very well. Shot trap, duck hunted, plinked out in the woods, shot nearly every firearm available in the Marines, and in the STA platoon, M40a1's and Barret M82's, and plenty of machine guns in other platoons. I even got to shoot some of them in combat, while being shot at! Most the firearms I own were built in the late 20's to the early 50's. Most of the guns I actively shoot are older than I am. But when I worked at a range I was able to shoot pretty much every new gun in every configuration as they hit the market. Now I shoot some limited action style shooting. It's interesting because I can come in right behind people shooting modern guns that are pretty tricked out, even though I'm using esoteric gear, and hardly get to practice enough.
Two decades of experience... You'd think I'd be a better shooter!
