Update 03/20/2013: 6.5mm PCC pressure testing data nearly complete, with Initial data as follows:
Maximum loads using throated chambers are within the maximum SAAMI standards for the 5.56mm NATO parent case (~62K PSI). Excellent accuracy and velocity were noted by the test-
ing lab owner.
While we did not request subsonic load testing for the 6.5mm PCC round, the lab did test the
the round using heavy 140gr. to 155gr. projectiles and were very surprised how well the round
did in testing.
Update 10/15/2012: Newest Load Data Info.,From 6.5mm PCC End User Bruce F, Thank You Bruce.
Bruce is using a 22" 6.5mm PCC Barrel, Virgin Lake City .223 Brass, formed & trimmed to 1.645" @ 30.0 grs. Case Capacity. Bruce has stated accuracy has been excellent over a wide range of loads.
These are Maximum Loads, Please use Caution and Reduce Loads by at least 10% .

Please use Safe and Proper Reloading Proceedures, Use at your own Risk .
Fireformed cases have a approximate case capacity range of 32.10 grs. to 33.45 grs, of water
depending on case manufacturer and chamber dimensions etc.
Please use extra caution when reloading, start low and work your way up until you have reached your desired accuracy or velocity goal or/if high pressure signs have started to develope,then back-off your charge by at least half a grain. Use this data at your own risk. The load data above is to be used as a basic guide, and are only to be used by experienced/knowledgable reloaders or those who are under the supervision of one.
We also offer free load developement support to our customers, just email us with your avail-
able projectiles and powders you have on hand and we will help you with your load developement
needs. We have three ballistic modeling computer programs to help you with new load develope-
ment. Of course it is to be used (the load data) with extra caution and at the users own risk.

How does the 6.5mm PCC round compare to the 6.5mm Grendel ?
Many have asked how does the 6.5mm PCC round compare to the 6.5 Grendel(R) round...Well, It Is not a apples to apples
comparison since the Grendel round uses a non .223 Remigton case, the Grendel case is much closer to the 7.62x39mm
case in terms of H2O case capacity (34 to 36 grains of H2O capacity) & case dimensions...While the .223 Rem. based
6.5mm PCC round has a non fireformed H2O case capacity of about 30 grains of H2O and a fireformed case capacity
of 32/33 grains of water depending on case manufacture. Also, the Grendel round requires a dedicated bolt and
magazine, while the 6.5 PCC does not, It uses the same bolt and magazines as the .223/5.56mm AR-15.

Barrel Break-In Proceedure
The following is a guide to "break-in" based on our experience. This is not a hard and fast rule, only a guide. Some barrel, chamber, bullet, primer, powder, pressure, velocity etc. combinations may require more cycles some less. It is a good idea to just observe what the barrel is telling you with its fouling pattern and the patches. But once it is broken in, there is no need to continue breaking it in.
Initially you should perform the shoot-one-shot-and-clean cycle for five shots. If fouling hasn't reduced, fire five more cycles and so on until fouling begins to drop off. At that point shoot three shots before cleaning and observe. If fouling is reduced, fire five shots before cleaning. Do not be alarmed if your seating depth gets longer during break in. This is typical of the “high” spots in the throat being knocked down during this procedure. It is not uncommon for throat length to grow .005”-.030” from a fresh unfired chamber during break in.

Design Draft of the 6.8mm PCC Round
This is the original design daft of the
two different versions of the 6.8mm
PCC cartridge, one is a non fireformed
version and the other is a fireformed
version with higher case capacity.
Case capacities are similar to the sister
6.5mm PCC round. Fireformed capacity
is approximately 33.51 grains of water.
Non Fireformed case capacity approx-
imately 30-31 grains of water
depending case manufacturer.

Very Low Drag (VLD) 6.5mm Projectiles
Pictured here is the Lapua
144 grain FMTBT projectile.
It is the longest 6.5mm pro-
jectile that is still practical in
the 6.5mm PCC cartridge. You
can still use longer and heavier
projectiles if you are looking
to use them for special purpose
uses like suppressor and subsonic
purposses etc.
Typical velocities with the Lapua
144 grain FMJBT projectile in the
6.5mm PCC case very from a low
of about 2,020 fps. to a high of
about 2,228 fps. These velocities
were gained from test barrels in
the 18" & 22" range, while the 16"
length will be a bit less in velocity.

AR-15 High Quality Billet Lowers
Pictured to the left is a billet 7075-T6 Aluminum AR-15 stripped lower (courtesy Mega Machine Shop Inc.) and is one
of the top five highest quality (In the author's humble opinion) AR-15 lower recievers available.
Many ask what is the difference between a forged and billet reciever ?
Well basically, billet lowers are manufactured from a solid block of extruded aluminum alloy. While forged recievers are made using a super heated aluminum alloy bars that are in a very malleable state and then is seated in a hammer forging press (with a couple of tons of pressure) and are then hammer forged Into to a pre-determined shape, and then is machined to final dimensions.
One destict advantage that billet lower
recievers tend to have is they tend to offer
heavy duty construction and offer more
features like adjustment/tension/
capture screws etc. for positive lock-up between
upper and lower half's etc. Billet
also can have Integrated trigger guards
machined as part of the reciever for added
strength etc., feature sometimes noat available w/ Mil-Spec forged lowers.

One destict advantage that billet lower
recievers tend to have is they tend to offer
heavy duty construction and offer more
features like adjustment/tension/
capture screws etc. for positive lock-up between
upper and lower half's etc. Billet
also can have Integrated trigger guards
machined as part of the reciever for added
strength etc., feature sometimes noat available w/ Mil-Spec forged lowers.
Billet Aluminum vs. Forged Aluminum
So the big question is, which is "better" ?
Well that depends on a couple of factors.
One of he biggest factors is price and budget, billet recievers are more costly vs. forged recievers (provided it's made of equal/same aluminum material/type like 7075- T6).
Billet generally gives you a slightly finer
finish, as it machines a little easier vs. forged.
As for tensile strength between the two types, there is generally no real difference if both are made of the same material/type.
So, as long as both the forged and billet recievers are of the same material and made to Mil-Spec. dimensions the differences are minimal.
6061 T-6 vs. 7075 T-6 Aluminum ?
When it comes to selecting between the two types I would definately select the 7075 T-6
aluminum vs. the 6061 T-6 aluminum. There are two primery reasons for this, One is the
tensile strength, and the other is corrosion resistance . 7075 T-6 aluminum has about a
70% higher tensile strength rating vs. the 6061 T-6 version.

DPMS/LR-308 (AR-10 length, .308 Win/7.62 X 51 mm) vs. AR-15 Pattern Lowers
To the left is a photo showing the size difference
between the two primery AR platforms that are
becoming the standard of American firearms
technology and great pride throught the Industry
and American military for over 40 years.
The design is still going strong throughout the free world, In particular the AR-15 platform in
both civilian and military circles.
Just look at all the calibers that are available for
the AR-15 rifle platform...

Visual Comparison of Various AR Platform rounds.
Here is a visual/photo of some popular
AR-15 & a AR-10/LR-308 rounds from
L to R:
.223 Rem/5.56mm NATO, 6.5mm PCC, 7.62x39mm, and the .308 Win/7.62x51mm NATO round (AR-10/LR308).
The 6.5mm PCC is able to surpass both the
.223 Rem/5.56mm NATO & the 7.62x39mm Russian round in Accuracy, Energy, BC, SD, Barrier Penetration and Long Range Trajectory.

The first Whitetail Deer taken with the 6.5mm PCC round.
This Whitetail Buck (Spike) was
taken at 110 yards with the 6.5mm
PCC round with the 120 gr. Speer
HotCor Softpoint, the round went
completly through the animal broad-
side and and exited the animal as seen
in the picture. The exit hole was near
.700" with massive blood loss. The
undressed weight was a surprising
155 lbs.
The 6.5mm PCC AR-15 Rifle pictured is
a 22" standard profile barreled upper
with a Japanese made Weaver 3-9x50mm adjustable riflescope. It is shown with a 5
round magazine.

Whitetail Buck & Doe taken at 242 Yards & 218 Yards
These two whitetails were taken by my
friend & field testing partner Paul with
his 18" Bbl. 6.5mm PCC rifle, and took
these wonderful animals at 242 &
218 yards in heavy woods. He used
the 100 gr. Nosler Partition loads.
Way to go Paul !
