Safe Use of Smokeless Powder for Small Arms
Safe Use of Smokeless Powder for Small Arms Propellant is designed to create gas when burned. The speed by which it creates gas is what we call, “Burn Rate”. You will hear about “faster powders” or “slower powders”. These descriptions refer ONLY to the rate at which relative propellants create gas. The burn rate of a propellant is controlled by surface area of the individual grains, density, particle size, energetic content, and burn rate modifiers (deterrents). It is impossible to tell the burn rate of a propellant by its physical traits alone. Burn rates of a propellant must be matched to the chamber and bore dimensions of a firearm, and the weight and resistance of a projectile. Many additional variables contribute to the correct balance of propellant burn rate and firearm requirements. Experts test these variables, using pressure-test barrels, and fired remotely. It is unwise and potentially dangerous for individuals to develop loads outside of established recipes. We call this, “Tickling the dragons belly”, and strongly advise against the practice. The ballistic output of your loaded rounds WILL change from many variables. Among them: Case length, case volume, primer type and brand, primer seating depth, temperature, altitude, atmospheric pressure, projectile weight, projectile seating depth, projectile form, projectile material, internal case capacity, propellant burn rate, charge weight, moisture contamination, residual solvent, bore conditions, case hardness, mouth crimp, bullet-pull, load length, powder lot, primer lot, projectile lot, firing pin or hammer force, and firearm. Propellants that look very similar, when loaded in a cartridge, can lead to disastrous results. Therefore, ensure your own safety by diligently following safe reloading practices. -
Firearm Safety 1. Always Keep the Muzzle Pointed in a Safe
FIREARM SAFETY 1. ALWAYS KEEP THE M UZZLE POINTED IN A S A F E DIRECTION This is the most basic safety rule. If everyone handled a firearm so carefully that the muzzle never pointed at something they didn’t intend to shoot, there would be virtually no firearms accidents. It’s as simple as that, and it’s up to you. Never point your gun at anything you do not intend to shoot. This is particularly important when loading or unloading a firearm. In the event of an accidental discharge, no injury can occur as long as the muzzle is pointing in a safe direction. A safe direction means a direction in which a bullet cannot possibly strike anyone, taking into account possible ricochets and the fact that bullets can penetrate walls and ceilings. The safe direction may be “up” on some occasions or “down” on others, but never at anyone or anything not intended as a target. Even when “dry firing” with an unloaded gun, you should never point the gun at an unsafe target. Make it a habit to know exactly where the muzzle of your gun is pointing at all times, and be sure that you are in control of the direction in which the muzzle is pointing, even if you fall or stumble. This is your responsibility, and only you can control it. 2. FIREARMS ACTIONS SHOULD BE OP E N AN D S H O U L D B E UNLOADED WHEN NOT AC TUALLY IN USE Firearms should be loaded only when you are in the field or on the target range or shooting area, ready to shoot. -

Weapon Employment Zone (WEZ) Analysis of the Optimized 300 Winchester Magnum Vs 338 Lapua Magnum with Various Ammunition Types By: Bryan Litz, Applied Ballistics LLC
Weapon Employment Zone (WEZ) Analysis of the Optimized 300 Winchester Magnum vs 338 Lapua Magnum With Various Ammunition Types By: Bryan Litz, Applied Ballistics LLC Background The specific intent of this WEZ report is to compare the ballistic performance of the 300 Winchester Magnum to the 338 Lapua Magnum with several available ammunition types. Understanding how these weapons compare in terms of hit percentage is important in the context of modern military applications. The recent upgrade of the M24 to the more modern XM-2010 platform would indicate that the 300 Win Mag is here to stay. [Ref 4] Ongoing activity with the Precision Sniper Rifle (PSR) development suggests that a platform based around the 338 Lapua Magnum class cartridge will be an option to consider someday as well. Understanding how these two options compare from a performance/hit percentage point of view, in combination with funding and logistics considerations will aid decisions regarding which platform to supply in various units and theaters. Ammo Types ABWEZDOC102 [Ref 2] provided a complete characterization of the 300 Win Mag, XM-2010 configuration including: A191, MK248 Mod1, and the Berger 230 OTM ammo types. Hit percentage was determined for these 3 rounds in high, medium, and low confidence environments. To avoid replicating these results, only the highest performing round (the Berger 230 OTM) will be considered here in comparison to 338 Lapua Mag 300SMK/ 250SMK/ performance.

DCB Frequently Asked Questions
Frequently Asked Questions “The bullet with the ‘ding’ cast in!” What is the "ding" that is cast in? The „DING‰ we intend to cast into every bullet is the sound of it hitting the target you are aiming at. Because we believe our bullets will shoot consistently and more accurately we have no doubt you, and more importantly the scorers, will hear more dings after you shoot. Realistically though, since the bullets are cast from a very soft alloy (see FAQ on ÂObturationÊ) the dings you see on the bullet surface are the result of simple bumping and tapping during the casting, sorting, sizing and packaging process. These do not in any way detract from the effectiveness or accuracy of the bullet. You will notice the bullets come in a vacuum formed bag to minimize more dinging in shipping and to keep the softer lubricant in the grooves, where it belongs. And finally, the dings are very consistent with the authenticity we are trying to match in the old bullets. Have you ever seen a perfectly surfaced antique bullet? We have been experimenting with the process and handling of these softer bullets for nearly a year and have discovered that there is hardly any way to commercially cast and process them without some „dings‰. Of course we could individually hand pack them into specially designed plastic or Styrofoam cradles, then seal and box them, but the cost would be so great we couldnÊt afford to shoot them ourselves, much less find a buyer in the market. We just hope you appreciate and enjoy the accuracy, authenticity, safety and economy the bullet provides, even with the ÂsilentÊ dings. -
Driving Bands
These are the bands placed around projectiles to prevent the forward loss of gas around the projectile. They are usually made from copper, gilding metal and sometimes sintered iron. The modern day has intruded here also and they will now be encountered in plastic versions. Their use and introduction can be traced back to the time when cylindrical projectiles first appeared. The original round cannonball because of its requirement to be loaded from the muzzle had no method of sealing the bore. In fact had the ball been tight enough to seal the bore you wouldn't have been able to load the weapon at all. All this changed when the Cylindro-ogival projectile arrived on the scene along with the not-new breech loading weapons. (They had been tried many years before but failed through the inability of the gunners to adequately seal the breeches). A round cannonball needs no stabilizing. Because of its spherical shape it is inherently stable. Ask any cricketer, golfer or baseballer. On the other hand the Cylindro-ogival projectile is inherently unstable. It will not fly very well at all unless it is stabilized in some way. The two basic methods of stabilizing an elongated projectile are: • Fin stabilization and, • Spin stabilization. Both of these methods are in current use in the world today. To provide adequate stability for a projectile using fins there needs to be FIN STABILISATION. some sort of protection for the fins. The arrow of your ancient bowman would not survive in the bore of a cannon without some form of protection. -
13055 Bullet Striations Kit
©2015 - v 4/15 13055 Bullet Striations Kit Teachers Manual INTRODUCTION A bullet or projectile fired from a rifled gun barrel is engraved with a mirror image of the gun’s rifling. Rifling is the process of making helical grooves in the barrel of a gun or firearm, which imparts a spin to a projectile around its long axis.This spin serves to gyroscopically stabilize the projectile, improving its aerodynamic stability and accuracy. Typically the rifled barrel contains one or more grooves that run down its length, giving it a crosssection resembling an internal gear- though it can also take the shape of a polygon, usually with rounded corners. Since the barrel is not circular in cross-section, it cannot be accurately described with a single diameter. Rifled bores may be described by the bore diameter (the diameter across the lands or high points in the rifling), or by groove diameter (the diameter across the grooves or low points in the rifling). Rifling is often described by its twist rate, which indicates the distance the bullet must travel to complete one full revolution, such as “1 turn in 10 inches” (1:10 inches), or “1 turn in 254 mm” (1:254 mm). A shorter rotational distance indicates a “faster” twist, meaning that for a given velocity the projectile will be rotating at a higher spin rate. A bullet is the projectile launched from a firearm upon its discharge. Modern bullets are usually conically shaped and made from lead or with a lead core surrounded by a copper alloy sheath, commonly called a jacket. -

LONDON E. & F. N. SPON, 125, STRAND. NEW YORK SPON & CHAMBERLAIN, 12, CORTLANDT STREET. 1892. MODERN GUNS AND SMOKELESS POWDER. PART I. INTRODUCTION. Gunpowder, the oldest of all explosives, has been the subject of many scientific investigations, sup- ported by innumerable experiments ; but Nature guards her secrets well ; and to this day it cannot be said that the cycle of chemical changes brought about by the combustion of gunpowder is thoroughly understood. Its original components vary, but are generally about 75 parts potassium nitrate, 15 parts carbon, and 10 parts sulphur, with other ingredients some- times added. These materials, when simply mixed together, burn with considerable vigour, but cannot rank as an explosive until they have been thoroughly incorporated, so that the different molecules are brought into such close proximity that each finds a neighbour ready and willing to combine on the smallest encouragement. Heat furnishes the necessary stimulus, by pro- 2 MODERN GUNS AND SMOKELESS POWDER. moting chemical activity ; and, when combined with concussion, the molecules are driven closer to- gether, and this intimate association accelerates their combination. The effect of mere concussion is shown to greater advantage when any of the more dangerous ex- plosives, such as iodide of nitrogen, are subjected to experiment.
