User Instructions for the Co-Ax® Primer Seater Issue 5
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. Crushed, broken-tipped, or protruding primers may be dangerous or cause variations in pressure. The case must be primed 1. Empty the primers from their package into the Seater’s tray. before adding new powder, so that your gun’s propellant powder is 2. Place the Large or Small Tube into the built-in channel, as shown in contained at the bottom of the case. Fig. 1. The anvil of the primer should face the slotted side of the Tube. -
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.

H.M.C.S.S. Cerberus, under the command of Captain Manderville, left her anchorage in the bay this morning, and after some practice off the Red Bluff, steamed away for the Heads. During the journey two targets were thrown out, the first being a triangle fixed up for the occasion at about 900 yards distance. The first round carried it away, and upon taking it on board it was found that it had been struck at the centre of the cross beam, and shattered to pieces. A small barrel was then put overboard with a red round to starboard. On account of the ebb tide the target drifted close to the steamer, and a tack had to be made so as to leave the target about 1,000 yards distant. -

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. -

Reloading Brass Shotshells Pt 2.Pdf
R.H. VanDenburg, Jr. Continued from Handloader No. 266 ext is the loading proce- ELOADING dure. One of the things un- R covered in all this is that Nbrass shells can generate higher velocities than paper or plas- tic, all other things being equal. So 1 if you plan to create a 3-dram, 1 ⁄8- ounce, 12-gauge load of 1,200 fps, for example, Brass you might not need any- where near the called for amount of powder. 38 www.handloadermagazine.com Handloader 267 PART II: Technical Tips Shotshells A lot of things factor into such events, such as bar- rel length and diameter, chamber length, atmos- pheric conditions, powder brand and grade, wad column and so forth. Waterfowlers might rejoice, but if you are competing in a timed event where re- covery between shots is important, this is a good thing to know. Typically, this occurs in the CBC shell only with black powder. With smokeless pow- der, performance is degraded. In the RMC shell, higher velocity occurs with both types of powder. The actual loading of brass shotshells differs from that which we are accustomed to with either metal- lic cartridges or modern shotshells. We have the luxury of loading one shell at a time as we typically load shotshells on a single-stage press or batch pro- cessing, i.e., completing one step on all the shells to be loaded before beginning the next step, as we usually load metallic cartridges. Either way the first aid we should obtain is a loading block. It is indis- pensable. -
