Catalog & Order Form Lead Bullet Technologies
Lead Bullet Technologies F.I.G ENT., INC. 78592 Hwy 2 Moyie Springs, ID 83845 Catalog & Order Form LBT PREMIUM MOLDS LBT bullet designs are the most copied cast bullets in the world, because, when they are cast in molds manufactured by LBT they are the most accurate bullets available! However, copying the profile of an LBT bullet by cherrying or conventional lathe boring processes, as all other moldmakers do, does not result in molds or bullets that live up to LBT accuracy standards! You see, the heart of all molds, which is the cavities, are produced at LBT with a one of its kind, ultra precision, custom designed, custom built, reducing tracer lathe. This only machine in the world was engineered for the single purpose of producing molds with precision that no available machinery could match. - In the 23 years of its existence, no moldmaker or machine, or mold cutting method has come close to producing LBT quality! - Because of this, the advantages of purchasing your molds from LBT are: 1. Molds which drop their bullets easier then any other mold. 2. Bullets which are better balanced than can be produced in any other molds, because they are round and sound, or free of voids-which equals: 3. Accuracy that is untouchable by bullets from other manufactures molds, even if they have copied our superior designs! Not to mention the design features in LBT molds which ensure void free bullets, flat bases, and extra long service life. LBT sprue plates are designed to minimize the shrink voids and air pockets which unbalance bullets and destroy accuracy, and are equipped with spring hold downs at two points, which prevent the sprue plate from lifting off the mold and causing finned and out of square bases. -

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. -

Loads Are Keeping the .44 Magnum at the Top of The
Pushing The Envelope Since the late 1990s Randy Garrett has been producing a 330-grain Super Hard Cast Long-Hammerhead at 1,385 fps. Custom gunsmith John Gallagher introduced me to it several years ago. I have found that if you run into John out hunting, he will likely have a cylinderful of Garrett 330s in his custom Ruger Bisley. When Hamilton Bowen went hunting up in Alaska last year, he was camping out in brown bear county. At night he slept with a Redhawk on a lanyard. No, it wasn’t a .475 or .500.

Dictionary of Explosives
DICTIONARY OF EXPLOSIVES BY ARTHUR MARSHALL A .C .G j., F.I.C., F.C.S. CHEMICAL INSPECTOR INDIAN ORDNANCE DEPARTMENT PHILADELPHIA P. BLAKISTON’S SON & CO. 1012 WALNUT STREET 1920 Printed in Great Britain INTRODUCTION It is a generation since a dictionary of explosives has been published, and, in the meantime, many new explosives have been introduced. It is hoped, therefore, that this small volume, giving concise information about these special materials, may prove useful to those who have to deal with them. In Cundill and Thomson’s “ Dictionary of Explosives,” issued in 1895, there arc many entries of the names of inventors and of mixtures which had been proposed but have never been used commercially, nor are likely to be. As modem explosives were then in their infancy, it was no doubt wise to insert all the available information whether it appeared to be important or not; but now it seems to me better to restrict the scope of the dictionary so as to keep its size within moderate limits. Practically only explosives with special or proprietary names are therefore dealt with here. For information concerning chemical substances, such as the nitro-toluenes and other nitro-compounds, reference should be made to the text-books on explosives and chemistry. A few words may, however, be said here about the nitro- celluloses. These are made by treating cellulose with a mix ture of nitric and sulphuric acids, and then purifying the product by washing it thoroughly with hot water. The variety of cellulose most used for this purpose is cotton, and the product obtained from it is frequently called nitrocotton, three special varieties of which are collodion cotton, pyro- collodion and guncotton (q. -

The Los Angeles Silhouette Club
The Los Angeles Silhouette Club Hunting with the .40-50 Sharps Straight By: Glen E. Fryxell The .40-50 Sharps Straight Contender For more on building the 40-50 Sharps Straight, load work- up & load data. The inspiration for this story can be found in J. D. Jones' project back in 1988 with SSK's custom Contender in the .338 Woodswalker. J.D. designed this round for walking around and kicking the bushes to see what came out, then be able to quickly deal a lethal 10" T/C Contender in 40-50 Sharps blow at short range. I read that article Straight. and liked the idea, absorbed the concept, and wanted to do something similar, except in .40 caliber, built around a moderately heavy cast HP. It has taken a while, but all in all it has come together rather nicely (good things take time...). Let's back up a bit. The Sharps rifle company is well known for making very accurate, large caliber, single-shot rifles that were used in the 1870s by the commercial buffalo hunters. There were a number of rounds that were used by the Sharps folks, but the last one to be introduced was the little .40-50 Sharps Straight, introduced in 1879, just a few years before Sharps went under. The original ballistics produced a 265 grain lead round-nose at 1410 fps. Not exactly laser-like in its ballistics (but note the similarity to the highly capable .44 Magnum). THIS was what I was looking for -- moderate pressure ballistics that were easily compatible with the Contender frame, along with a simple rimmed straight case with a powder column suitable for a handgun-length barrel. -

And Lastly, by a Taper-Reamer for the Gas-Che
CONSTRUCTION OF NAVAL GUNS roughing slope bit; fourth, by a finish packed bit; fifth, by a finish slope bit; and lastly, by a taper-reamer for the gas-che<;k slope. The finishing bits are long, of the exact diameter of the chamber (that is, ground so as to bore to the exact diameter) . For guns having the enlarged chamber, as the 6-inch, Mark VI, and 12- inch, Mark III, a different method is pursued. The chamber is nrst roughed out with a hog bit, .then two packed bits are used and two slope bits. The powder chamber being larger than the mouth (or entrance) must be bored with a special boring bar and tool. This bar is hollowed, and is provided with a cutter that can be set out any desired amount by means of internal gearing worked from the outside clear of the breech. Finally the gas-check slope is finished with a taper-reamer. The chambers for R. F. guns are tapered to receive fixed ammu nition. Usually they are roughed out to desired taper, using a boring bar carrying a cutter fed in by hand, the rear end of bar being thrown out of line with gun's axis. Chambers having a straight part, and the compression slope, are roughed out with a packed bit. The finishing cut is now taken with a long packe;:l bit, or reamer, ground so as to bore the chamber to exact dimen sions. This bit mllst be very accurately made and carefully in spected by the officer supervising the work. -
