I think if you google .50 AE, you will find it is likely a .50 Action Express. Never seen the gold plated version though... Not to brag, but have shot one pistol a bit more powerful, the .500 Smith and Wesson. Used to write for hunting/gun mags, and got to try out some neat stuff. After I missed the target, you could watch the slug bounce along the desert like a bowling ball! All for business, you know. Ammo sales are incredible south of the line from all I have seen. Not much in the way of pure plays in the ammo space in the stock market. Winchester Remington and Hornady all pvt, I think. ATK (publicly traded) puts out Federal, CCI and several other brands, as well as supplies (I believe) all the small arms ammo the US military shoots. I'd like a commision off that! However, sporting ammo is a small % of their sales, and providing rocket engines for missile systems and the space shuttle kind of dilute their sporting ammo sales. It was ATK, by the way, the McDonald Detweiller was trying to sell that Cdn satalite to till the gov't squashed the deal.

Ruger (RGR) and Smith and Wesson are publicly traded under RGR and SWHC.

Good shooting, and investing.
