And Velocities
It is not the purpose of this manual to delve deeply into the complex sub-
ject of chamber pressure or how it relates to all firearms. There are, however,
some basic differences between a muzzleloader and a modern cartridge
firearm. The reader must understand and respect these differences if he or she
is to use their T/C muzzleloader in a safe manner.
Shooting muzzleloading firearms requires rethinking all that you have
learned about firearms. It requires discipline to cope with the require-
ments of being a reloader and rifleman at the same time. It requires strict
adherence to the instructions set forth in this booklet. FAILURE TO
FOLLOW THESE INSTRUCTIONS MAY CAUSE DAMAGE TO THE
FIREARM AND INJURY AND/OR DEATH TO THE SHOOTER OR BY-
STANDERS AND DAMAGE TO PROPERTY.
Odd as it sounds, your safe introduction to muzzleloading firearms re-
quires a good deal of reverse thought. Our forefathers, trained in the use of
muzzleloaders, had little difficulty using the products of their day or adapting
to improved concepts as each new idea presented itself in a normal progres-
sion. The transition from flint lock to cap lock to breech loader each represent-
ed a step forward toward a more technically sophisticated era. Users of
firearms had hundreds of years to adapt to these changes. In a single lifetime,
no one was exposed to drastic change.
The muzzleloading enthusiast of today, however, has been trained in the
use of cartridge firearms. To safely use a muzzleloader he must adjust his
thinking backward - bridging hundreds of years of product development - in
one giant step! Those reading this booklet must face the realization that the
design of a muzzleloading firearm is rooted in tradition. In other words, a
manufacturer of muzzleloading firearms, while he does have the benefit of
using modern steel, proper heat treating and other technical advances, does
not have the option of drastically altering a design which is centuries old. To
use a muzzleloader safely requires considerable mental adjustment on the part
of today’s shooter.
Modern cartridge firearms depend heavily upon the strength of a brass
cartridge case to seal the chamber and to safely confine expanding gas. Equal-
ly it is the cartridge case which holds the bullet in a fixed position, confines
the powder charge to a given volume and controls headspace. Modern car-
tridge firearms are designed to withstand high working pressures since these
same pressures make possible the high velocities, flat trajectories and
increased range of modern ammunition. Yet, the modern firearm is no stron-
ger than the cartridge case that is used in its chamber. If the case ruptures, the
primer punctur

ed, hot powder gases under
