I have heard a few things about the Lorenz rifle, namely that a). it was the third most common small arm used during the Civil War and b). that it was not nearly as well received as either the Springfield 1861 or the P53 Enfield due in large part to quality control issues rising from a lack of interchangeability in parts due to them being hand fitted, and also that many firms did work of dubious quality when reboring the barrels to accept the .58 caliber ammunition in common use on both sides. However, I do take these with a grain of salt as I have not yet read any historically verified sources on many of the small arms used during the conflict. Just how common was the Lorenz rifle among Union and Confederate forces? And what did the troops who used them think of them?
The Muster 1854 System Lorenz rifle was the third most commonly used firearm over the duration of the Civil War. Well in excess of 200,000 were imported by the Federals. MAJ Huse purchased 100,000 for the Confederates, with somewhat more than 80,000 having made it through the blockade. Other suppliers provided additional numbers to the Confederates, but documentation is unclear. So far, I can document that at least 550 Federal regiments were armed with some number of them at some point in time during the War. Additional numbers were used by home guard units who saw combat. Confederate regimental numbers are more difficult to pin down due to the lack of records. But, in 1863-5 a third or more of the Army of Tennessee was armed with Muster 1854 System Lorenz rifles.
The only interchangeable muzzle loading rifle muskets were Springfields, and imported London Armoury made Enfields. ALL other rifle muskets were the product of artisanal technology which used parts hand and machine made to semi-standard gauges.
Some of the ".54" to .58 caliber conversion work did not meet standard. But, MAJ Hagner and CPT Crisptin at the New York Ordnance Office accepted bored out arms -- .59 and .60 caliber -- at a reduced price which should have been rejected. The question is, was the Federal Army so desperate for anything that went bang that they had to accept them or was Hagner corrupt. As an old Federal criminal investigator I would dearly love to have a shot at Hagner's financial records.
Among the larger problems were:
The Federal .54 caliber ammunition at .537 inches was seriously undersized for the ,547 inch bore of the Muster 1854 rifle. Despite this, the Federal Ordnance Department blindly and stupidly insisted that U.S. standard .54 caliber ammunition could be used in Muster 1854 rifles. This resulted in accuracy problems.
Fixed sighted firearms are designed to shoot a standard bullet at a standard velocity, and the sights are graduated for that standard bullet and velocity. If you change the cartridge, the sights no longer match the cartridge. By issuing Muster 1854 rifles with Federal ammunition without changing out the sights on the rifles, the Federal Ordnance Department guaranteed that the sights would not be calibrated to the cartridges they were issuing.
Neither the Federals nor the Confederates EVER translated the Austrian manual for the Muster 1854 rifle. The manual provided explanations for all of the problems complained of by the troops. The manual, for example, explained that the breech of the rifle required very careful cleaning because it was slightly relieved to permit the bullet to slug up and then be squeezed down in a variation of the progressive rifling concept. Never having read the manual, and never having been taught how to properly clean their rifles, the troops complained that the weapons fouled at the breech. They may also have collected lead at the breech since they had not been designed by Ritter von Lorenz to be fired with Minie balls. Firearms are designed as a system, and you screw with it at your peril. When the U.S. Army changed the powder load in 5.56 mm ammunition during the Viet Nam War without adequate testing, M-16 rifles literaly tore themselves apart. But, the officials who made that decision no doubt got suitably meritorious gongs for their "service."
Marksmanship training on both sides was essentially non-existent. Being a "farmer" or a "hunter" by itself does not produce the skill set necessary to shoot military firearms at militarily useful distances under the pressure of combat. A similar situation is true of modern troops who confuse the possession of a penis and testicles with an ability to shoot. Federal units that actually trained with their Austrian rifles generally liked them.
