The discharge of ammunition in a fire
earm that is not designed
d to shoot th
hat ammunittion can
be
e dangerous
s and can re
esult in serious injury or death
d
to the user and/orr bystanderss, as well as damage
to
o the firearm
m. This unsafe condition is caused by
b an excesssive build-up
p and/or release of high-pressure
ga
as in a firearrm's chambe
er, barrel and/or action beyond
b
whicch the firearm
m is designe
ed to
w
withstand. Th
herefore, in the interest of safety, yo
ou should usse only amm
munition of th
he caliber or gauge
de
esignated by
y the firearm
m manufacturer for use in
n that firearm
m. Markingss indicating tthe correct ccaliber or
ga
auge of amm
munition to be
b used in a firearm are usually foun
nd on the fire
earm’s barre
el, frame or rreceiver.
O
One way to verify
v
that you are using the correct ammunition
a
is to check tthe head sta
amp on the
ammunition to
o confirm tha
at it matches
s the caliberr or gauge m
markings placced on the firearm by the
firrearm’s man
nufacturer. Some
S
types of ammunitiion do not ha
ave marking
gs on the head stamp off the
ca
artridge. In that case, check the orig
ginal ammun
nition packaging to dete
ermine its caliber. If you have any
do
oubt about the
t caliber of the ammun
nition, you sh
hould not usse the ammu
unition until yyou have it e
examined
byy a qualified
d person who
o can determ
mine its calib
ber. Remem
mber just beccause a roun
nd of ammun
nition can
fitt into a firearrm's chambe
er, barrel or action does not mean itt is safe to usse that amm
munition in th
he
firrearm.
D
Due to the av
vailability of many
m
differe
ent shapes and
a sizes of ammunition and firearm
ms, there
are countless
s unsafe amm
munition-fire
earm combin
nations such
h that a comp
prehensive list of unsafe
e
co
ombinations
s is neither fe
easible, nor practicable. Below is a list of some unsafe com
mbinations th
hat
are well know
wn because of
o somewha
at similar cha
amber and a
ammunition d
dimensions.
If the caliber or
o gauge is not clearly marked
m
on th
he firearm, o
or if it appearrs the origina
al markings on the
firrearm have been altered
d or modified
d in any way
y, do not use
e the firearm
m as serious injury or dea
ath could
re
esult to the user
u
and/or bystanders,
b
as well as damage
d
to th
he firearm.
S
Similarly, SAA
AMI has not published voluntary
v
rec
commended practices orr proceduress for re-cham
mbering
off firearms. It is possible
e the re-cham
mbering of a firearm mayy not have b
been done properly or m
may not
ha
ave been prroperly mark
ked on the firrearm. If the
e caliber or g
gauge markiing is missin
ng or altered in any
w
way, you should not use the firearm. You should
d instead havve the firearrm examined
d by a qualifiied
pe
erson to dettermine what caliber or gauge
g
ammu
unition can ssafely be use
ed in that fire
earm.
