Jury Education

This function encompasses having the jury see the case through the expert’s eyes.  “My opinion is ..” type testimony is not sufficient.  When the expert teaches the jury, they will see the case as the expert sees it and, assuming the jury is composed of reasonable people, they will make the same decision as the […]

Machine Shop

This set of skills goes far beyond what the ordinary expert can do.  LTC Alphin created all the machinery and procedures for the manufacture of A-Square products (including rifles, handguns, cartridge cases, bullets, etc).  Though he no longer operates factories, he has a personal machine shop wherein he can create almost any exemplar, or duplicate […]


The expert must have the photographic skills to visually capture, and show to the jury, any item he needs to explain.  LTC Alphin has the skills and equipment to accomplish this. Alphin was admitted as a member in the British Royal Photographic Society and a past member of the British Institute of Professional Photographers (due […]

Gunfight Dynamics

This involves discerning how the man-weapon interface plays out, and interacts, when in crisis or emergency situations. LTC Alphin’s skills in this area allowed him to precisely reconstruct a fight over disputed property (see case of Tennessee vs. Pallet Handler).  He also precisely interpreted the scene and the remains of a professional hunter whose rifle […]

Utilization of Firearms

This involves the selection of which firearm for which use.  This includes selection of a firearm for defense in its different forms (licensed concealed carry, residence, apartment, etc.), for hunting (varmints, waterfowl, upland birds, big game, etc.), for sport (trap, skeet, free pistol, 3 position rifle, etc.) and casual recreation (plinking, practice, etc.).

Capabilities of Firearms and Ammunition

This extends exterior and terminal ballistics into the field of what can the firearm and ammunition actually do.  This is necessary not only for training but also for shooting incident scene reconstruction and for explaining scenes to a jury.

Training for Use of Firearms and Ammunition

This field of endeavor includes not only methods of instruction but also imparting to the user/shooter enough information to enable safe use of the firearm but also to extract the maximum capabilities in terms of range, volume of fire, and terminal effect.  Included within this is training for specific disciplines, such as skeet shooting at […]

Metallurgy of Ammunition

This area of metallurgy encompasses the exact alloys of brass, lead, and other materials which are used in ammunition and how each one is selected to give the correct properties necessary for a round of ammunition.  This includes gradient of anneal and other issues which lead to a final end-use item that functions correctly.

Metallurgy of Firearms

This area of endeavor addresses the exact metallurgical composition of each and every part of the firearm.  Parts may be optimized for their function by changing the alloy and hardness.   This further branches out into the use of polymers and other man made materials for use in firearms.

Ammunition Manufacture

This discipline addresses how each cartridge case is manufactured, from its starting point as a coin, along with how the projectile is manufactured (which could start as a coin or a bar), how the primer is manufactured, and how the propellant is manufactured.  For shotguns, this would also deal with the shot pellets and the […]
