500 Round Factory Sealed Case Speer LE 24475 - .223 Rem 75gr Gold Dot Soft Point Patrol Rifle Duty Load in 20 round boxes
is the new Speer Law Enforcement .223 75 gr Gold Dot JSP (GDSP) that
was announced at the 2015 SHOT Show. Offered are factory-sealed cases
of 500 rounds (25 boxes of 20 rounds each).
This cartridge is recommended for carbines or short barreled rifles with a length of 16" down to 9." Short barrels should have a 1:7 twist. A 1:9 twist may not stabilize the bullet. With barrels longer than 16," the bullet may break up.
This round is designed for SBRs with a barrel length no longer than
16," preferably shorter, and a rate of twist of 1:9 or faster,
Federal Tactical LE223T3 will also perform
well in a short-barreled rifle, but also will perform better than the Speer
24475 in rifle length barrels (longer than 16"), and in barrels with a twist of 1:9.

Following in the footsteps of their successful 62/64 grain Gold Dot LE
223 Remington ammunition, Speer has introduced a 75 grain version of
their blind-to-barriers “bonded” soft-point ammunition (#24475).
ammunition is loaded in nickel-plated brass cases with crimped and
sealed primers, however, there is no sealant at the case mouth. The
load is charged with “ball” powder. The head-stamp reads: “SPEER 15 223
The form of the 75 grain Gold Dot is just what you
would expect it to be; a longer and heavier version of the 62/64 grain
Three 10-shot groups of the Speer LE 75 grain Gold Dot ammunition were fired in a row with the resulting extreme spreads:
a 10-shot group average extreme spread of 1.07”. The three 10-shot
groups were over-layed on each other using RSI Shooting Lab to form a
30-shot composite group. The mean radius for the 30-shot composite
group was 0.32”.
The muzzle velocity for the 10-shot
string of the Speer LE 75 grain Gold Dot ammunition fired from the 20”
Colt barrel was 2652 FPS with a standard deviation of 11 FPS and a
coefficient of variation of 0.42%.
SPEER Gold Dot Duty Rifle brings proven bullet technology to rifle
platform. The Gold Dot® bullet was the first high performance,
bonded-core bullet and has since set the bar for duty ammunition. Gold
Dot rifle bullets are optimized to ensure expansion out of barrels down
to 10" at a wide variety of velocities out to 200 yards. This kind of
performance greatly increases the capabilities of duty rifles and gives
a distinct advantage when it matters most. In addition, these new loads
boast outstanding feeding in short, very short and standard length AR
platforms. Gold Dot rifle bullets are constructed using Gold Dot
technology. The process of joining the jacket and core one molecule at
a time eliminates the potential for the leading cause of bullet
failure—jacket/core separation. Exact tolerances and
unprecedented bullet uniformity of jacket thickness give Gold Dot rifle
loads outstanding accuracy. In addition, these loads feature flash
suppressed propellants and a muzzle velocity of up to 3000 fps.

"The official BC is 0.373, by the way." pistol-forum.com
"Today, I fired a round into water jugs
(milk-jugs) at a paced 95m. My paces are pretty accurate (about 10m +-
over 400m, measured w/surveyor wheel, numerous times, when I lived out
in S TX). I used my 16.1" DDM4, suppressed. The round expanded
VIOLENTLY, and penetrated the same number of jugs as at 15m. Three,
with the round coming to rest in the 4th, after ALMOST breaking out of
the outer most side. The bulk of the fragments shown were found in the
2nd and 3rd jugs. This round is still moving "too fast" at 100ish yards
to retain 100% of its mass. It is my opinion that the BC really is
around 0.4, and this round has some legs on it!"
"Here it is, shown next to the one fired at 15m,
for reference (the fragmented round is, ironically, the one fired at
100-ish yards):" (See photographs above)
it's definitely growing on me. The BC is a game-changer in barrier
blind ammo, IMO."
"Based on an 1800fps expansion floor, it should
open up out to 300 yards. More "cool" data, is that it PERFECTLY
matches my Nightforce NXS 1-4 FC-2's drop hash-marks. Zeroed at 100,
the bottom of the circle is 300m, the top of the triangle 400m, and the
bottom of the triangle, 500. Within 1 MOA.
Also, it's very accurate, and bucks wind well
due to the high BC. It drops into "pistol territory" (velocity-wise)
further out than RA556B or XM556FBIT3, as well.
Literally the only thing it gives up is a few
hundred FPS from muzzle to about 150 yards, and then the difference is
academic and it pulls ahead around the 200 mark.
Looking at my expanded open-air 100 yard shot
though...should it HAVE
more MV? I'm leaning towards "no"."
"We will be testing this in the relatively near
expectations for this round) "Superior long range
performance, better intermediate barrier capability--particularly auto
glass, closer trajectory to other 70+ gr ammo."
"Both the 55 & 62/64 versions have performed well, so it it
likely that this will carry on in the same fashion--but you never know
until it gets tested..."
"Allegedly, the Gold dots don't have the leading issue secondary to how
little lead is exposed. According to Dr. Roberts, most of the leading
came from non-bonded rounds."
The jacket is not bonded, but molecularly-fused, allowing terminal
performance comparable to the more costly bonded bullets. You get
exceptional performance at a reasonable price. The process of joining
the jacket and core one molecule at a time eliminates the potential for
the leading cause of bullet failure-jacket/core separation. It also
ensures impressive weight retention through barriers as tough as
It is an excellent all-around .223 cartridge combining accuracy with
barrier penetration. It will function perfectly in AR15s chambered for
5.56mm as well as those that are chambered only for .223 Rem. The 75
grain cartridge is best used with a rifling twist rate of 1:7 or 1:9.
When it is fired in a rifle with a slower rate of twist, the longer
75-grain bullet can yaw up to 70 degrees in free trajectory through the
air, substantially degrading accuracy.
