At the CCI part of the Vista Outdoors exhibit at the SHOT Show, some new shot cartridges caught this correspondent's eye. There were three displayed: a 10mm offering using 109 grains of #9 lead shot, a 9mm using 43 grains of Hevi Bismuth, non lead shot; and a .38 Special using 80 grains of Hevi Bismuth, non lead shot.
The 10mm is to satisfy those with 10mm handguns who find a shot cartridge useful for their needs. The Hevi Bismuth loads are to satisfy customers who want to be certain about their status on the law, where lead shot is prohibited. A CCI representative said most of the demand for the Hevi Bismuth loads comes from the western United States. Testing of the Hevi Bismuth loads show comparable results to current lead loads.
This correspondent has sources which have experimented with the Tungsten Super Shot (TSS). The performance of TSS is far, far beyond lead shot. TSS is extremely dense, 18.3 grams per cubic centimeter, compared to about 11.3 grams per cubic centimeter for lead shot. TSS is about 60% more dense than lead, which gives it a tremendous ballistic advantage. TSS appears to be a natural for pistol shot cartridges, which are primarily limited by the small volumes of shot available. Because of the difference in density, a similar shot cartridge could fit in 60% more shot. Because of the combination of hardness and density, shot sizes can be dropped by at least two levels, for similar terminal effects.
This correspondent asked: Why not switch to TSS? Pistol shot shells are already relatively expensive, because they are produced in such small numbers. The increased costs of using TSS shot would primarily be in the cost of the shot. Lead costs about $2 per pound, TSS about $42 per lb. The amount of shot in a pistol shot shell is small, about 1/4 ounce for the larger calibers. With TSS, it could be increased by 60%, to .4 ounces. 16x2.5 is 40 shots per pound, or about $1 more per shot. With small, hard shot, serious patterns at further ranges become likely. Dropping two shot sizes roughly doubles the pellet count.
The people at CCI can read the research and do the math better than this correspondent. They have tested TSS in pistol caliber shotshells. My source told me the results are much superior to lead shot. The problem is not a technical problem. TSS and pistol shot shells are a beautiful match. The problem is not an economic one. Pistol shot shells are used in small enough quantities, most people can afford another dollar a cartridge. The problem is legal. Tungsten Super Shot has been ruled by the ATF to be an armor piercing material. It is banned for use in pistols because of the old "cop killer" legislation, passed when Joe Biden was a senator. Anyone who produces a shot shell for pistols, using TSS, is likely to be shut down by the ATF.
It is possible an exemption, as especially useful for sporting purposes, could be granted. It is highly unlikely under the Biden administration.
This is technological progress stopped by bureaucratic political games. Such is the problem with passing legislation based on emotion and technological ignorance. Emotion and ignorance was the combination used by President Biden, when he helped pass the "cop killer" armor piercing bullet ban as a senator.
