User Instructions for the Co-Ax® Primer Seater Issue 5 1.0 GENERAL INFORMATION 4.0 FILL PRIMERS IN FEED TUBE Co-Ax Primer Seater allows for fast, easy seating with a built-in primer Primers for U.S. cartridges come in two diameters — large (0.210”) and flipper and loading tray. It seats primers flat and coaxially with the small (0.175”) — and two general types — rifle and pistol. Rifle primers cartridge case for accurate alignment and penetration. have more rigid cups and a hotter flash than pistol primers. The unique design allows the operator to eliminate “slop” when working The Primer Seater comes with two sizes of the Feed Tube with a specific cartridge, translating into consistent seating, reliable (011521-011LG and 011521-011SM). To fill the Feed Tube with primers, ignition, and reduced misfires. you may use the Primer Seater tray or the Primer Tube Loader (sold separately), as described below. Case priming is a critical handloading operation because, in order for ammunition to perform efficiently, consistent powder ignition is 4.0.1 FILL PRIMERS IN BUILT-IN TRAY mandatory.

High-Speed Measurement of Firearm Primer Blast Waves
High-speed measurement of firearm primer blast waves Michael Courtney, Joshua Daviscourt, Jonathan Eng U.S. Air Force Academy, 2354 Fairchild Drive, USAF Academy, CO, 80840 [email protected] Amy Courtney Force Protection Industries, Inc., 9801 Highway 78, Ladson, SC 29456 [email protected] Abstract: This article describes a method and results for direct high-speed measurements of firearm primer blast waves employing a high-speed pressure transducer located at the muzzle to record the blast pressure wave produced by primer ignition. Key findings are: 1) Most of the lead styphnate based primer models tested show 5.2- 11.3% standard deviation in the magnitudes of their peak pressure. 2) In contrast, lead-free diazodinitrophenol (DDNP) based primers had standard deviations of the peak blast pressure of 8.2-25.0%. 3) Combined with smaller blast waves, these large variations in peak blast pressure of DDNP-based primers led to delayed ignition and failure to fire in brief field tests. Keywords: rifle primer, blast pressure, primer strength, muzzle velocity variations I.

THE EFFECTS OF PHYSICAL FLASH HOLE DEVIATIONS ON FACTORY- GRADE RIFLE AMMUNITION by NICOLAAS MARTIN SCHRIER A THESIS Presented to the Faculty of the Graduate School of the MISSOURI UNIVERSITY OF SCIENCE AND TECHNOLOGY In Partial Fulfillment of the Requirements for the Degree MASTER OF SCIENCE IN EXPLOSIVES ENGINEERING 2015 Approved by Paul Worsey, Advisor Gillian Worsey Jason Baird iii ABSTRACT The objective of this research is to determine the effect of dimensional and positional changes of the primer flash hole on the performance of factory-grade rifle ammunition. The studied variables were flash hole diameter, offset from center, and orientation of the offset in the primer pocket. Cartridge performance was quantified by measuring muzzle velocity, chamber pressure, and target grouping size (precision). Five different flash hole diameters were tested for both the Remington .223 and Winchester .308 calibers: 1.4mm, 2.0mm (the Fiocchi standard), 2.4mm, 2.8mm, and 3.0mm. -
A Sharp Little Affair: the Archeology of Big Hole Battlefield
A Sharp Little Affair: The Archeology of the Big Hole Battlefield By Douglas D. Scott With Special Sections by Melissa A. Connor Dick Harmon Lester Ross REPRINTS IN ANTHROPOLOGY VOLUME 45 1994 Published by J & L Reprint Company 410 Wedgewood Drive Lincoln, Nebraska 68510 Revised for PDF publication June 2009 Acknowledgments First and foremost we wish to acknowledge and thank Hank Williams, Jr. for his interest and financial support. The National Park Service seldom has the luxury of conducting an archeological research project that is not tied to some development project or some overriding management action. Mr. William's support allowed us to pursue this investigation for the benefit of the park without being tied to a specific management requirement. His support did allow us to accomplish several management goals that otherwise would have waited their turn in the priority system. This project has had more than its fair share of those who have given their time, resources, and knowledge without thought of compensation. Specifically Irwin and Riva Lee are to be commended for their willingness to ramrod the metal detecting crew. They volunteered for the duration for which we are truly grateful. Aubrey Haines visited us during the field investigations and generously shared his vast knowledge of the Big Hole battle history with us. His willingness to loan material and respond to our questions is truly appreciated. Former Unit Manager Jock Whitworth and his entire staff provided much support and aid during the investigations. Jock and his staff allowed us to invade the park and their good-natured acceptance of our disruption to the daily schedule is acknowledged with gratitude. -
Federal Ammunition for Civil War Breechloading Carbines and Rifles
Federal Ammunition for Civil War Breechloading Carbines and Rifles Dean S. Thomas According to the "Statement of ordnance and ordnance stores purchased by the Ordnance Department from January 1, 1861, to June 30, 1866," the United States Army procured more than 427,000 assorted breechloading carbines and rifles during this period.' Additional quantities were purchased from the manufacturers by various Northern states, volunteer regiments, and individual soldiers. In all, more than twenty different brands found their way onto regimental ordnance returns, and each, with rare exception, required their own peculiar form of ammunition. Captain James G. Benton of the Ordnance Department described these weapons in his book, Ordnance and Gunney: The term "breech-loading" applies to those arms in which the charge is inserted into the bore through an opening in the pered by gas leakage at the breech joint-or lack of obtura- breech; and, as far as loading is concerned, the ramrod is tion.

Firearms and the Decline of Violence in Europe: 1200-20101
Firearms and the Decline of Violence in Europe: 1200-20101 Carlisle E. Moody College of William and Mary College of William and Mary Department of Economics Working Paper Number 158 January 2015 1 I would like to thank Stuart Ivinson and Jonathan Ferguson of the Royal Armouries Museum in Leeds for all their help. COLLEGE OF WILLIAM AND MARY DEPARTMENT OF ECONOMICS WORKING PAPER # 158 January 2015 Firearms and the Decline of Violence in Europe: 1200-2010 Abstract Personal violence, has declined substantially in Europe from 1200-2010. The conventional wisdom is that the state’s monopoly on violence is the cause of this happy result. I find some evidence that does not support this hypothesis. I suggest an alternative hypothesis that could explain at least some of the reduction in violence, namely that the invention and proliferation of compact, concealable, ready-to-use firearms caused potential assailants to recalculate the probability of a successful assault and seek alternatives to violence. I use structural change models to test this hypothesis and find breakpoints consistent with the invention of certain firearms. JEL Classification: N43, K42 Carlisle E. Moody Economics Department College of William and Mary Williamsburg, VA 23187-8795 [email protected] I INTRODUCTION It is now taken for granted that crime, especially personal violence, has declined substantially in Europe from the Middle Ages to the present. ( Johnson and Monkkonen, 1996; Sharpe 1996; Malcolm 2002, Pinker 2011.) The best source of the data demonstrating this fact is Eisner (2003) who compiled a large data set on homicide rates from 1201 to 1971 from several European countries. -
A 3D Tour Handgun History Dan Lovy
A 3D Tour Handgun History Dan Lovy I have a new toy, a 3D printer. I am amazed at the level of quality compared to its price. I'm printing out robots, cartoon characters and as many Star Trek ship models as I can find. The darn thing is running almost 24/7 and all my shelving is filling up with little plastic objects. First let me state that I am not a gun enthusiast. I own no fire arms and have been to a firing range once in my life. I believe that we have too many and they are too accessible, especially in the U.S. That having been said, I also have a fascination with the technological change that occurred during the industrial revolution. In some ways we are still advancing the technology that was developed in the late 19th and early 20th century. Fire arms, especially handguns, offer a unique window into all this. Advancement did not happen through increased complexity. A modern Glock is not much more complex than a Colt 1911. The number of parts in a pistol has been in the same range for nearly 200 years. Cars on the other hand gained complexity and added system after system. Advancement did not happen through orders of magnitude in performance. A 747 is vastly more capable than the Wright Flyer. One of the basic measures of a pistol is how fast can it shoot a bullet, that parameter has not really changed much, certainly not as much as the top speed of a car. -
