Hello Fellas,
I believe that the forum members here would be Interested in a new AR-15 wildcat and the forum guys here seem to be quite sharp
and are not condescending types like on some other forums.
I would like to Introduce a new .223 based, AR-15 specific, 6.5mm round called the 6.5mm Patriot Combat Cartridge (6.5 PCC).
I have worked on this cartridge for the better part of two years, and
have been lucky
to see it succeed as far as AR-15 .223 based wildcats are concerned.
I had been frustrated after I had purchased a SSK Industries complete
upper in 6.5mm called the SSK 6.5 MPC . I was very happy once I had
finally received the upper from SSK to only become
extremely disappionted in the actual field results
when compared to the SSK website listings for
the MPC cartridge loads in terms of velocity/power
levels (they were not even close).
So a few months pass and I wind up talking to a friend in Alabama and he convinces me to develope my own design based on the
.223 Rem. case. I agreed to do so (I have a Mechanical Enigineering background) and told him he would need to do the
initial field testing since he had his own private 100 yard range and plenty of wild game
around like wild hogs and deer.
Fast forward several months later, sent in all the design blueprints, reamer prints to the reamer manufacturer for the reamer and gages
another set to the die manufacturer and the last set to the barrel manufacturer.
Again, fast forward several more month's our two test barrels come
in, one in 18" length (my fiends Paul's) and mine in 22" length. I sent Paul all the equiptment he needed, projectiles, powders, dies, ballistic
programs, chronograph etc. The barrels were designed on a stainless steel 416R barrel blank with a three grove stress relieved
Polygonal bore with a 1:8 twist to handle the long VLD pills.
Initial testing was better that expected, I had designed the cartridge
to meet or exceed the power level of the 7.62mm Russian
round with better accuracy and range than the X39mm.
Thankfully the 6.5mm PCC surpassed the design objectives
originally developed for it. Accuracy has been very good to excellent
with nearly all loads tried so far.
Here is a quick summary of the various real world field results in both
testing phase and 6.5mm PCC end user results (velocity, energy)...
120 grain Speer HotCor Spitzer Softpoint:
-----------------------------------------------------------------------
18" bbl. velocity: 2,441 fps., energy: 1,589 ft/lbs, H335 powder
22" bbl. velocity: 2,520 fps., energy: 1,693 ft/lbs, H335 powder
-----------------------------------------------------------------------
-----------------------------------------------------------------------
100 grain Hornady Spitzer Softpoint:
----------------------------------------
18" bbl. velocity: 2,708 fps., energy: 1,629 ft/lbs, H335 powder
22" bbl. velocity: 2,807 fps., energy: 1,750 ft/lbs, H335 powder
-----------------------------------------------------------------------
-----------------------------------------------------------------------
85 grain Sierra Varminter Hollowpoint
-----------------------------------------
18" bbl. velocity: 3,054 fps., energy: 1,762 ft/lbs, H335 powder
22" bbl. velocity: 3,138 fps., energy: 1,860 ft/lbs, H335 powder
------------------------------------------------------------------------
------------------------------------------------------------------------
144 grain Lapua Scenar FMJBT (.636 BC/G1 !)
---------------------------------------------------
18" bbl. velocity: 2,102 fps., energy: 1,414 ft/lbs, H335 powder
22" bbl. velocity: 2,240 fps., energy: 1,605 ft/lbs, H335 powder
The 18" and longer barrels perform quite well in both velocity and
accuracy w/ H335 powder, the 16" to 18" barrels perform very
well with the faster powders like AA1680 etc.
Below are some pics of Deer (both Bucks & Does) taken with the 6.5mm PCC round.
The Buck was taken at 217 yards & the Doe at 242 yards. Thanks Paul. Paul used a
100 grain Pro Hunter, complete pass through in both animals.
Below is a young Buck taken at 110 yards with a 120 grain Speer HC,complete pass through
massive exit wound with much blood loss...
Hope it wasn't to boring for everyone here...
