| This is in response to the discussions in BiggerHammer
about head seating on the .50 Cal BMG round. Regardless of how much
of the crimp ring is showing on the base of the bullet, the correct
way to determine if the round is in spec is to measure the overall
length. Mil Spec for the .50 BMG
is 5.450 (+ 0.000/ - 0.050 ) inches long. In order to feed reliably
in the M2 gun it is best to be at the high side of the limit. Each
round is run through automatic machinery where the overall length
is preset to 5.440 inches. Some of the crimp ring will show when
set to this length. Remember we are not selling "Match Grade"
ammo and the projectiles are not sealed (Glued) in place like military
ammo is. We try to keep the cases crimped tightly against the projectile
but you can only do this so tight before you start to deform the
case neck.
TNW Firearms, Inc. is committed to customer satisfaction. If you
ever find a TNW Firearms round that is out of spec or fails to fire
we will replace it for free (limited to stock on hand). We understand
the investment that you have in your firearms and ammunition. The
craftsmen at TNW Firearms, Inc. are dedicated to making sure you
are satisfied. Our ammunition is assembled from military surplus
components with the original primer and powder. The unfired cases
are resized and a surplus projectile is placed in the case. The
cases is crimped against the projectile but there is no sealant
as shown in the drawing. Some cases show slight denting or discoloration. This low cost
ammunition is great for machine guns or target practice and although
our testing has shown it to be accurate it is not “ match grade“
ammo. If you require match grade there are many suppliers that will
help you at $3.00 to $5.00 per round.
Some other items of Interest:
1. Tracer or Incendiary rounds do not harm the barrel. The tracer
element is timed to fully “light“ at 50 to 500 yards.
Well out side your firearm. Due to the long burn time of the tracer
element in the 50 BMG there is always the chance of starting an
accidental fire. More so than with an Incendiary round. The Incendiary
round is a Chemical powder of Barium and Aluminum that is contained
inside the projectile. The only time the compound will react is
when it is compressed by the penetrator during impact. The reaction
time is less than one-tenth of a second.
2. Corrosive Primers: Primers manufactured previous to 1952 were
corrosive in nature due to their chemical makeup. This is only a
problem if you do not plan on cleaning your gun after each shooting
session. The only advantage to the corrosive primers is that they
have a longer shelf life. A round that was manufactured in the 1940´s
for the most part is still very reliable today.
3. Fifty Caliber firearms and Ammunition will be banned: There is
a great political move to demonize the fifty caliber firearm and
the enthusiasts that enjoy them. Now that they have beaten the “Assault
Gun“ Issue to death there is a political void in the never ending
assault on the Second Amendment. This Void will probably be filled
with firearms who chamber the 50 BMG cartridge! There are several
bills and riders in Congress now that will reclassify the firearms
as NFA weapons. To be honest there is only one small group out there
that is truly fighting for the 50 caliber BMG and that is the Fifty Caliber Shooter's Association (435)
527-9245 . They are volunteers that have organized lobby efforts
to make sure that our rights are not “Discounted“ further.
If you are a 50 BMG Enthusiasts then you are a “Lobbyist“.
If you do not have time to walk the halls of Congress trying to
explain to them “what end of a gun you wish to be on“ then
send FCSA money. They have several raffles going on for new 50 cal
rifles to help entice you to send in funds. Funds that intern will
help keep all Americans free from more “INFRINGING“ legislation.
As for the ammo all of the fun stuff has already been banned!! Last
October some congress “woman“ (who will go unnamed) put
in a rider to the Defense Bill stating that no AP of any type will
be sold to the public from our Arm Forces. The Government will now
have to pay to have something with a market value destroyed at great
tax payer cost. As there was already existing law that no Incendiary
or Tracer can be imported (even if it was made in the U.S.) this
little unpublished rider leaves us with only what was on the shelves
of the dealers at the time of the ban. The 50 cal. BMG AP supply
is going to dry up. TNW Firearms, Inc. is currently sold out of
BMG AP and Ball and has a limited supply of the various API
and APIT ammo in stock now, but (like the 30-06 AP we used to carry
and are now sold out of), there is no foreseeable future supply.
