High Power Rifle, also called XTC from "Across the Course", is a shooting sport using fullbore target rifles which is arranged in the United States by the National Rifle Association of America.
 The sport is divided into classes by equipment, and popular types of matches include Service Rifle, Open, Axis and Allies and metallic silhouette.
 The term High Power Rifle sometimes also includes the international shooting disciplines of Palma and F-Class by the International Confederation of Fullbore Rifle Associations (ICFRA) which are represented by the NRA in the United States.
Fullbore target rifle (TR) is a distinctively British and Commonwealth of Nations shooting discipline that evolved from Service rifle (SR) shooting in the late 1860s, and is governed in the UK by the rules of the National Rifle Association, UK (NRA).
 Similar rules are used in several Commonwealth countries, but the issue in 2006 of the rule book of the International Confederation of Fullbore Rifle Associations (ICFRA) has provided an alternative basis for the administration of the sport.
"I'll give you my gun when you pry (or take) it from my cold, dead hands" is a slogan popularized by the National Rifle Association (NRA) on a series of bumper stickers.
 It is a variation of a slogan mentioned in a 1976 report from the Senate Judiciary Committee Subcommittee to Investigate Juvenile Delinquency: "I Will Give Up My Gun When They Peel My Cold Dead Fingers From Around It."
 The original version did not originate with the NRA, but with another gun rights group, the Citizens Committee for the Right to Keep and Bear Arms, based in Bellevue, Washington.
 It, along with "If guns are outlawed, only outlaws will have guns", is a slogan that is often used by gun owners and their supporters in discussions of gun control in the United States.

Don Bernard Kates Jr., (January 26, 1941 – November 1, 2016) was an American lawyer and research fellow with The Independent Institute in Oakland, California who focused on promoting gun rights.
 His scholarship and litigation played important parts in the modern renaissance of the Second Amendment.
 Additionally, Kates played a major role in bringing together scholars and opinion leaders.
 Along with Stephen Halbrook, Kates deserved the primary credit for making the Second Amendment scholarship an important topic of modern scholarly interest.
 His books include "Armed: New Perspectives On Gun Control", "Restricting Handguns: The Liberal Skeptics Speak Out", "Firearms and Violence: Issues of Public Policy", and "The Great American Gun Debate: Essays on Firearms and Violence" (with Gary Kleck).
 As a civil liberties lawyer he has been retained by the National Rifle Association to represent gun owners attacking the constitutionality of certain firearms laws.
 The "Washington Post" described Kates as the "Johnnie Cochran" of the pro-gun lobby, noting his polemical attacks on public-health research on firearms injuries and writing that Kates "has muddied the waters of truth so thoroughly that wading into them is a daunting task."
 Kates also wrote extensively on criminological issues related to firearms.
 Among his most influential policy articles is “Guns and Public Health: Epidemic of Violence or Pandemic of Propaganda?”
 which appeared in a symposium issue of the "Tennessee Law Review" in 1994.
 His 1983 article in the "Michigan Law Review" was the first time that a top-10 law journal published a detailed historical analysis of the original meaning of the Second Amendment.
