Hagelberg FH 50 is a .50 BMG, single shot bolt-action bullpup precision rifle manufactured by Hagelberg Arms.
 The rifle is designed for both target shooting and law enforcement use, and comes in two lengths, variant L (Long) and variant K (Short).
 The rifle can also come with a sound suppressor and short rang back-up sights.
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".
The .350 Remington Magnum was introduced in 1965 by Remington Arms Company for the Model 600 rifle.
 It was later offered in the Model 660 and Model 700 (one numerous various caliber configurations) rifles but was discontinued as a regular factory chambering in 1974 after a poor sales record.
 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.
The AS50 is a .50 BMG sniper/anti-materiel rifle manufactured by British firearms producer Accuracy International.
 The AS50 enables operators to engage targets at very long range with high accuracy using explosive or incendiary ammunition.
 The AS50 employs a gas operated semi-automatic action and muzzle brake, allowing for lower recoil than the AW50 bolt-action rifle and faster target acquisition.
 The rifle is highly transportable, ergonomic and lightweight.
 It can be disassembled in less than three minutes and serviced without tools.
The Canadian Swing Championships is an annual event held since 2002 to showcase swing dancing in Canada.
 It is held near Montreal over the Victoria Day weekend.
 Before 2005, the event was called the Eastern Canadian Swing Championship, but was renamed when no equivalent event was started in Western Canada and the ECSC became the de facto national championship.
The B96 Pepsi SummerBash is an annual concert typically held on a Saturday in June, in the Chicago area.
 First held in 1992 and presented by Chicago radio station B96, the concert has been title-sponsored by Pepsi in recent years.
 In 2016, the event was held at Allstate Arena in the suburb of Rosemont.
 Previously, the event was held at Toyota Park in Bridgeview from 2006 to 2015.
 In 2006, the SummerBash was the first non-soccer event held at the stadium.
 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.
 Noted for featuring several marquee performers in a day-long series of sets, the event is considered to be one of the premier annual radio station concerts in the U.S. by many in the radio industry, along with events such as the 102.7 KIIS-FM's Jingle Ball, Wango Tango, Z100's Jingle Ball, and rock station 105.7 The Point - St. Louis' Point Fest.
 The success of the annual SummerBash concerts allowed the station to also begin a holiday variation of the event called the B96 Jingle Bash.
Anvil firing (also known in the USA as an "anvil launching" or an "anvil shooting") in the USA is the practice of firing an anvil into the air with gunpowder.
 In the UK this is where black powder is filled onto the top of the Anvil and ignited.
 If the Anvil did not shatter it was deemed safe to use.
The Boomershoot is a long range precision rifle event held near Orofino, Idaho, each year in late spring.
 The targets are filled with explosives at ranges from 375 to .
 Shooters are allowed to engage as many targets as they are able during the all-day event.
 Nearly every year the amount of explosives has increased; in 2004, the amount of explosives put out for people to shoot was greater than all of the other years combined.
 In 2005, new targets were introduced with smaller amounts of explosives to reduce window breakage in the surrounding countryside.
 In recent years, the event has also featured an explosive fireball and an Anvil firing to start the event and entertain the participants.
