Recoil Action: Firearm action that uses the force of the recoil to provide energy to cycle the action. Roller-delayed Blowback: A type of fi rearm action where rollers on the sides of the bolt are driven inward against a tapered bolt carrier extension. This forces the bolt carrier rearward at a higher velocity and delays movement of the bolt head. Rolling Block Action: A fi rearm action where the breech is seeled with a specially shaped breechblock able to rotate on a pin. The breechblock is locked in place by the hammer preventing the cartridge from moving backwards when fi red. Cocking the weapon allows the breechblock to be rotated to reload the weapon. Short Recoil Action: Action where the barrel and slide recoil together a short distance before they unlock and separate. The barrel stops quickly, and the slide continues rearward, compressing the recoil spring and performing the automated extraction and feeding process. During the last portion of its forward travel, the slide locks into the barrel and pushes the barrel back into battery. Slide Action: A fi rearm action where the handgrip is moved back and forth along the barrel in order to eject a spent cartridge and chamber a new one. This type of action is most common in shotguns and is also used in some rifl e designs. It is also called pump action. Snaphance: A method of fi ring a gun that uses a fl int set in the hammer that when the trigger is pulled causes the fl int to strike the frizzen to create a shower of sparks to ignite the priming powder. -

Prediction of Shot Start Pressure for Rifled Gun System
Defence Science Journal, Vol. 68, No. 2, March 2018, pp. 144-149, DOI : 10.14429/dsj.68.12247 2018, DESIDOC Prediction of Shot Start Pressure for Rifled Gun System N.V. Sudarsan#,*, R.B. Sarsar#, S.K. Das@, and S.D. Naik# #DRDO-Armament Research and Development Establishment, Pune - 411 021, India @DRDO-Defence Institute of Advanced Technology, Pune - 411 025, India *E-mail: [email protected] ABSTRACT Determination of short start pressure (SSP) for gun system has always been of paramount interest for gun designers. In this paper, a generalised model has been developed for theoretical prediction of SSP for rifled gun system using dimensional analysis approach. For this, parameters affecting the SSP of the gun like rifling dimensions, driving band dimensions, material properties of driving band, projectile mass and diameter are taken into consideration. For a particular case of large caliber rifled gun system, the model is established using linear relations among dimensionless groups of parameters. The model has been validated by data available from the open literature. Keywords: Driving band; Forcing cone angle; Coefficient of friction; Rifled barrel; Dimensional analysis 1. INTRODUCTION assumed that SSP is engraving pressure of driving band and Internal ballistics (IB) deals with the processes that take its value for normal guns lies between 25 MPa to 40 MPa. The place inside the gun which is expressed in terms of pressure model developed by Schenk10, et al. has described that SSP is an travel, peak pressure and muzzle velocity as an output. IB outcome of the resistance, which depends on various properties study is carried out with either lumped parameter model or of driving band like material properties and geometry, as well gas dynamic model1-3. -

From the defeat of General Edward Braddock and the use of flank companies of riflemen in the French and Indian War, to the use of long rifles against Ferguson and the death of General Simon Fraser in the Revolutionary War at Saratoga, to the War of 1812 when British General Robert Ross was shot on the way to take Baltimore in 1814 and when long rifles were instru- mental at New Orleans in January 1815, up to the modern wars with the use of such arms as the Accuracy International AX338 sniper rifle, sharpshooters have been crucial in the outcome of battles and campaigns. I wish to dedicate this discussion to a true American patriot, Chris Kyle, a much decorated Navy Seal sniper whom we lost in February of this year, having earned two silver and four bronze stars in four tours of service to his country. He stated that he killed the enemy to save the lives of his comrades and his only regret was those that he could not save. He also aided his fellow attackers at bay; harassing target officers and artillerymen disabled veterans for whom he worked tirelessly with his from a long-range; instilling psychological fear and feelings Heroes Project after returning home. -
John Dahlgren the Plymouth Rifle
JOHN DAHLGREN And THE PLYMOUTH RIFLE Marc Gorelick, VGCA The author thanks Tim Prince of College Hill Arsenal (www.collegehillarsenal.com) and Cliff Sophia of CS Arms (www.csarms.com) for the use of their photographs. Few Americans today know who John Dahlgren was, or the role he played in the Civil War. Most Civil War and navy history buffs who recognize his name identify him as a Union Admiral and ordnance expert who developed a number of naval cannon. Indeed, for his achievements in developing naval cannon he became known as the “father of American naval ordnance.” But to the gun collecting community Dahlgren was also a small arms expert and the inventor of the unique Plymouth Rifle. Photo courtesy Tim Prince, College Hill Arsenal, www.collegehillarsenal.com DAHLGREN’S NAVY CAREER John Adolphus Bernard Dahlgren was born on November 13, 1809 in Philadelphia, the son of Bernhard Ulrik Dahlgren, the Swedish Consul in Philadelphia. Like another Swedish-American, John Ericsson, the inventor of the screw propeller, turret and ironclad monitor, Dahlgren was to have a profound effect on the U.S. Navy. Dahlgren joined the United States Navy in 1826 as a midshipman. He served in the U.S. Coastal Survey from 1834 to 1837 where he developed his talents for mathematics and scientific theory. He was promoted to lieutenant, and after a number of cruises was assigned as an ordnance officer at the Washington Navy Yard in 1847. Dahlgren was in his element as an ordnance officer. He excelled as a brilliant engineer and was soon given more and more responsibility.
