What is a Pritchett Bullet?
The Pritchett, or Metford-Pritchett, bullet was used in the .577" calibre family of muskets in the British army from the introduction of the
P-1853 Enfield musket in 1853. Basically the Pritchett was a hollow based smooth sided conical bullet that was loaded paper patched in the musket. The
diameter of the un-patched bullet was .568", but in 1858 the diameter
was reduced to .550". It weighed 530 grains.
Most bullets of this type are called minié balls
today. The US Army used a similar ball in
their .58 calibre muskets, but this had grease grooves and was loaded
without paper patching. However, a lot of Pritchett bullets saw service
in the American Civil War. Huge amounts of cartridges with Pritchett bullets
were imported from the trade in England, and confederate armouries produced
many variations of the Pritchett.
What is the "Modern Pritchett Bullet Mould"?
Pritchett balls.
The "Modern Pritchett Bullet Mould" is basically a slightly shortened version
of the original Pritchett projectile. Why shorten it? Well, from the beginning
the P-1853 Enfield rifle muskets had a three groove barrel with a 1 in 78"
rifling twist. In addition, the
P-1856 and P-1858
Army Short Rifle plus several carbine variations had barrels rifled with
this twist.This is a very slow twist for a heavy conical projectile. In
1858 the British Royal Navy adopted a two band rifle, the P-1858 Naval Rifle
which had a five groove barrel and a 1 in 48" twist. The accuracy was superior
compared to the three groove 1 in 78" twist rifles. The British Army adopted
the 1 in 48" twist in their P-1860 and P-1861 Army Short Rifles. The P-1861
Cavalry Carbine and the P-1861 Artillery Carbine also had the new fast twist.
The "Modern Pritchett Bullet" is made to stabilize better in slow twist
muskets, both original and replica. It can also be used in the fast twist
muskets. All .58 calibre muskets and rifles, such as the 1855, 1861 and
1863 Springfield, CS Richmond Musket, 1863 Remington ("Zouave")
etc. can shoot this bullet.

The mould.
The bullet moulds are produced by Lee Precision to my specifications.
The mould blocks are machined from aluminium and handles are included.
The mould is made in 25 copies. If you have questions, use this
contact
form. I planned to have another batch of mould made, but Lee no longer makes hollow based or hollow point moulds. This means that I have to get another maker to make the new batch.
The price is $72 + shipping. Sold out!
