Optimization of Production Process of Frangible Bullets Based on Bismuth Powder
Advances in Military Technology Vol. 14, No. 2 (2019), pp. 189-196 AiMT ISSN 1802-2308, eISSN 2533-4123 DOI 10.3849/aimt.01224 Optimization of Production Process of Frangible Bullets Based on Bismuth Powder V. Minh Do 1, X. Son Bui 1*, J. Komenda 2, R. Vítek 2 and P. Skalický2 1 Faculty of Weapons, Le Quy Don Technical University, Hanoi, Vietnam 2 Faculty of Military Technology, University of Defence in Brno, Czech Republic The manuscript was received on 29 November 2017 and was accepted after revision for publication on 20 June 2019. Abstract: The article deals with the pressing process of the samples from bismuth powder, which were used in place of the bullet in order to optimize the frangible bullets manufacturing process. Cylindrical samples with a diameter of 9 mm were compacted by cold pressing in a cylindrical rigid die without sintering. Various pressing conditions (the changing of pressing force, pressing velocity and dwell time) were applied for compacting the sam- ples. After compaction, the axial strength of the samples was tested to determine the optimal manufacturing process of the frangible bullet based on the bismuth powders. Keywords: bismuth, frangible bullet, green strength, green density, powder metallurgy, pressing force, pressing velocity 1. Introduction Powder metallurgy technology is also used in manufacturing the ammunition for fire- arms. In the commercial frangible cartridges, the frangible bullets are made of various kinds of metal powder, e.g. Cu, Fe, W, etc., where Cu is the most widespread. These metals are less ecologically harmful than lead. However, iron and copper easily cor- rode in water-rich tissues, whereas copper is toxic at high concentration in the body. -

Intro to Reloading
Intro to Reloading This introductory manual will cover the basics of handloading ammunition. It will include information regarding necessary equipment, required materials, and the reloading process. This is not intended to be a comprehensive guide. Reloading is an in-depth, complex subject. This guide is a starting point for absolute beginners. Further information should be sought out for your specific calibers you are reloading, your specific brand and models of equipment, and your specific reloading components and materials. Follow all instructions that come with your equipment and materials. When someone who has never reloaded their own ammo looks into it, the needed equipment list is daunting and expensive. It is the intention of this guide to make reloading seem easy and accessible. Anyone, even children, can reload ammunition if shown the steps. My 8 year old is more than eager to help me de-prime, drop powder, or resize shells. Hopefully the knowledge presented here will increase your confidence when it comes to starting your reloading journey. [2] Socialistra.org Why Reload? Self Sufficiency: A decade ago, the generally accepted wisdom was “You will always be able to find .22lr. You will always be able to find .223. You will always be able to find .30-06. You will always be able to find XYZ.” After Sandy Hook in 2012, that all changed. For YEARS afterward, certain kinds of ammo were simply non-existent on store shelves. In this Time of Trump, it may not seem to make sense to spend $.10-$.25 more on each round you would make vs just buying the factory ammo. -

Terminal Ballistics
Terminal ballistics Terminal ballistics, a sub-field of ballistics, is the study of the behavior and effects of a projectile when it hits its target.[1] Terminal ballistics is relevant both for small caliber pro- jectiles as well as for large caliber projectiles (fired from artillery). The study of extremely high velocity impacts is still very new and is as yet mostly applied to spacecraft design. 1 General An early result is due to Newton; the impact depth of any .32 ACP full metal jacket, .32 S&W Long wadcutter, .380 ACP projectile is the depth that a projectile will reach before jacketed hollow point stopping in a medium; in Newtonian mechanics, a pro- jectile stops when it has transferred its momentum to an equal mass of the medium. If the impactor and medium 2.1.1 Target shooting have similar density this happens at an impact depth equal to the length of the impactor.

Copper Bullets, Ballistically by Wayne Van Zwoll
The following review was accessed at: http://www.rmef.org/Hunting/RifleCart/Rifles/CopperBullets.htm on 8/15/2012. Copper Bullets, Ballistically by Wayne van Zwoll Lead-free bullets have been around for decades. Now they’re the rage. But how do they perform? For bullets, lead is logical. It is dense, malleable and relatively cheap. When a hollow-base bullet upstaged the patched round ball in the 1840s, the physical properties of lead were essential to its success. The pressure of powder gas in the base cavity expanded it upon firing, for a tight bore fit and good accuracy. Lubricated with mutton fat or beeswax, the Minie ball, was issued to Union troops for their Enfields during our Civil War. After metallic cartridges and breech-loading rifles appeared, an expanding bullet base was no longer needed. In the 1890s, repeating rifles by John Browning and Paul Mauser put muzzleloaders on the skids. High-energy smokeless propellants supplanted black powder, hiking bullet velocities. Increased bore friction deformed traditional lead bullets, however, and accuracy fell off. Solution: a jacket to insulate the lead. The .30-06 cartridge was conceived in 1900, when engineers at Springfield Armory began work on a battle rifle to replace the .30-40 Krag- Jorgensen. The Model 1903 Springfield fired a 30-caliber rimless round with a 220-grain bullet at 2,300 fps that closely matched the 8x57 Mauser and its 236-grain bullet at 2,125. A year later Germany switched to a 154-grain 8mm spitzer at 2,800 fps. The Americans countered with the Ball Cartridge, Caliber .30, Model 1906, hurling a 150-grain bullet at 2,700. -

Flat Base Or Boatail How and Why: the Bullet Does the Actual Killing. The
Flat Base or Boatail how and why: The bullet does the actual killing. The rifle is simply a means to deliver the bullet to the target. So, a basic knowledge of bullets seemed to be a prerequisite for studying rifles. As hunters, we put a lot of thought into the tips of our bullets. Roundnoses, spire points, plastic tips and such are all worried over to ensure that the bullet we’re using is right for the game we’re hunting. But have you ever given as much consideration to the other end of your bullet–the base? In the scheme of things, the base of your bullet probably isn’t going to make any more of a difference between a hit or a miss, a clean kill or a wound, than the bullet tip, but it is something to consider if you’re on a once-in–a-lifetime hunt and want to eliminate as many variables as possible that could leave you standing there wondering what went wrong if a trophy animal bounds away seemingly unscathed. There are generally two types of bases on hunting bullets, flat base and boattail. The practical differences between them may not be what you think. Both have their benefits, and their drawbacks. For example, when it comes to pure accuracy, flat base bullets are inherently more accurate than boattails, and that’s why you see the “short range” Benchrest shooters using them. The reason is because it’s easier to make their bases perfectly square with the sides of the bullets than it is to make boattails perfectly concentric and on straight. -
