The break-open single or double barrel shot gun generally--
1. Feeds by hand
LOADS
2. Locks
3. Fires
4. Unlocks
5. & 6. Extracts and Cocks
7. Ejects.
UNLOADS (this will be done either automatically or by hand, it will depend
on the type of firearm).
SHOTGUN ammunition: A cartridge or cartridges are fed into the barrels by hand. The barrels are then closed, allowing action to LOCK. The shotgun at this point is LOADED AND READY TO FIRE; EXTREME CAUTION MUST BE EXCERCISED AT THIS TIME.
In order to fire the shotgun a simple squeeze of the trigger is all that is required. Once fired the locking lever is moved to the right allowing the action to break open (UNLOCK). The fired or unfired cartridges as the case may be, may then be removed from the chamber (UNLOAD). This then completes functions 1-7.
THE BOLT ACTION FIREARM
In general the term bolt action refers to rifles of
all calibres. However we must remember that some shotguns are also bolt
actions. This type of shotgun is not very popular these days but many of
them were sold in days past. The bolt action, like all other actions, generally
follows the same 7 steps of operation--
1. Feeds (cocks)
Bolt forward
LOADS
2. Locks
Bolt handle lowered
3. Fires
4. Unlocks
5. Cocks
Bolt handle lifted
6. Extracts
Bolt rearward
UNLOADS
7. Ejects
Pushing the bolt forward and turning it down feeds
a round into the chamber and locks the action. The firearm can now be fired
by squeezing the trigger. Lifting the bolt handle and pulling it to the
rear completes functions 5 to 7.
Bolt action firearms may be single shot or fitted with one of several types of magazine. They are sometimes referred to as bolt action repeaters.
SAFETY CATCHES
To carry a loaded firearm relying on the Safety Catch
is looking for a disaster to happen. We must remember that Safety Catches
are only a supplement for Safe Handling practises.
They are mechanical, they are subject to failure at
anytime, they can be accidentally released and should never be solely relied
upon.
THE LEVER ACTION FIREARM
This type of firearm is more likely the most recognised
firearm of all, it has been seen in many Western movies and was dubbed
the "GUN THAT WON THE WEST".
This type of action has proved to be very popular
with all age groups. It can be purchased in both "CENTRE FIRE" and "RIM
FIRE" calibres. This type of firearm, because of its external magazine,
its exposed hammer and the difficulty of ensuring that the breech and the
magazine are empty, requires an even higher level of safety than other
types of firearms. If you are going to use a Lever Action Firearm, then
ensure that you are fully aware of the operating and Safety procedures
associated with this type of firearm.
The Lever Action generally--
1. Feeds
LEVER UPWARDS
LOADS
2. Locks
3. Fires
4. Unlocks
5. Extracts
LEVER DOWNWARDS UNLOADS
6. Cocks
7. Ejects
The lever, which is attached to the bolt, is moved
upward, feeding the round into the chanber and locking the action. The
firearm may now be fired by squeezing the trigger. The lever is then moved
downward and completes functions 4-7.
Again we must remember that there are several things
about a lever action firearm that require special attention.
1. EXPOSED HAMMER, which may catch on clothing or
scrub and inadvertently become cocked.
2. TUBULAR MAGAZINE. Some models may be of some considerable
age. The magazine spring which has been continually compressed and expanded
may have become weakened, rusted through or broken.
The magazine tube may have been dented or have dirt
or other matter in it causing a round to hang up, or in fact a round may
have even been slighty bent again causing a hang up. If a round hang up
in the magazine you may work the action several times an think that there
are no further rounds in the magazine when in fact there is still a round
in the magazine. A knock at a later time could cause this round to become
free and be accidentally fed into the breech and cause an unintentional
firing of the firearm. ON EVERY OCCASION PRIOR TO PUTTING A FIREARM WITH
A TUBULAR MAGAZNIE AWAY AFTER USE YOU SHOULD THAT THE MAGAZINE IS TOTALLY
FREE OF AMMUNITION.
3. COCKING THE FIREARM. We must remember taht every
time that the lever is operated (pulled down and returned up) the firearm
IS COCKED (the hammer is fully back). Extreme care must be exercised at
this time.
THE SLIDE OR PUMP ACTION FIREARM
The pump or slide action generally--
1. Feeds
2. Locks
SLIDE FORWARD
LOADS
3. Fires
4. Unlocks
5. Extracts
SLIDE REARWARD UNLOADS
6. Cocks
7. Ejects
The fore end, which is attached to the action bar
and also to the bolt, is pushed forward feeding a round into the chamber
and locking the action. The firearm can now be fired by squeezing the trigger.
The fore end is then pulled to the rear, completing functions 4 to 7.
THE SLIDE OR PUMP ACTION
This is very similar to the "Lever Action" and is
operated by moving the fore end of the stock instead of a lever. It is
also knwon as a "Trombone Action".
As with the lever action this is known as a "sliding
block". Usually it has a tubular magazine and is susceptible to the same
problems of denting and spring weakening as previously described for Lever
Action levers.
Particular care is required with this firearm because
of--
1. EXPOSED HAMMER. (Some models are produced with
exposed hammers).
2. TUBULAR MAGAZINE. (Some models are available with
rotary and box type magazines.)
You must remember, as with the Lever Action, if your
firearm has a tubular magazine or an exposed hammer, you must exercise
extreme causion when unloading the firearm to ensure that the magazine
is completely empty.
THE SEMI-AUTOMATIC OR SELF-LOADING FIREARM
The semi-automatic action generally--
1. Feeds
2. Locks
BLOCK FORWARD LOADS
3. Fires
4. Unlocks
5. Extracts
BLOCK REARWARD UNLOADS
6. Cocks
7. Ejects
There are two distinct types:
(a) THE OPEN COCKED POSITION
In one type, after firing a round, the block remains
to the rear. When the triggeris squeezed, automatically-
- the block moves forward
- a round is fed into the
chamber
- the firing pin strikes the
round
- the block is driven to the
rear again, leaving a cocked firearm, ready to fire again.
(b) THE CLOSED COCKED POSITION
After firing a round the block automatically moves
forward again to feed the next round into the chamber. When the trigger
is squeezed--
- the firing pin strikes the
round
- the block then moves rearward,
compressing the return spring
- the block is driven forward,
feeding the next round
- the firing pin is compressed,
leaving the firearm loaded, cocked and ready to fire.
YOU MUST REMEMBER WITH THIS TYPE OF FIREARM EVERY
TIME A ROUND IS FIRED IT RE-COCKS ITSELF AND IS READY TO FIRE AGAIN.
This type of firearm is frequently manufactured with
a tubular magazine, so again you must exercise caution when unloading.
Make sure that the magazine is completely empty.
