Ok as some of you know I've been lusting after a 458 Socom for a while now. Sniper03 and JonM turned me on to this incredible caliber while I was looking at the 45 Raptor. Here's the thread on that discussion if anyone is interested;

After much though and debate I'm building now. Finally decided that this deserves its own build thread as I'm going to build both upper and lower. The 458 needs some mods that make it different from a normal AR15, hence the thread.
Design:
I've decided on a light weight AR with a 16" barrel, free float handguards and flat top upper. Some parts have already been ordered, I'll link those in below. The gun is going to be used as a hog gun, with an emphasis on one shot take down power.
Ammo;
I'm also setting up to reload the ammo as this round has a hefty price tag. Dies, brass and an initial selection of bullets have been acquired about two months ago. I've also ordered two LEE lead molds, from Midway, for a 340 grain flat nose, and a 405 grain flat nose. Also got the factory crimp die for the round as its not in the basic 458 Socom die set. 100 rds of new brass, as I need somewhere to start...
