Hagelberg FH 50: Hagelberg FH 50 is a .50 BMG, single shot bolt-action bullpup precision rifle manufactured by Hagelberg Arms.

Marksman: A marksman is a person who is skilled in precision shooting, using projectile weapons, usually with a rifle but most commonly with a designated marksman rifle or a special application rifle, to shoot at long range targets.  In popular and historical usage, "sharpshooter" and "marksman" are considered synonyms.  Within the shooting sports and military usages today, however, sharpshooter and marksman refer to distinctly different levels of skill, which are never conflated.  Specifically, in the US Army, "marksman" is a rating below "sharpshooter" and "expert".  Four levels of skill are generally recognized today in both military and civilian shooting circles: unqualified, marksman, sharpshooter, and expert.  Marksmanship badges for the three qualified levels are commonly awarded to both civilian and military shooters who attain proficiency in shooting higher than "unqualified".

Remington has also offered the Model Seven MS from their Custom Shop and a limited edition 700 Classic in recent years chambered in .350 Remington Magnum.  Remington began chambering the round in the new Model 673 Guide Rifle in 2002.  This caliber was also sold as a chambered size configuration in a line of long range shooting and competition handguns, the Remington XP-100.

Other venues that have played host to the event include the First Midwest Bank Amphitheater in Tinley Park, Joliet Raceway, and Maywood Park, all in the suburban Chicago area.
