6.5mm Patriot Combat Cartridge (6.5 PCC), AR-15 Specific 223 based wildcat

Thanks for your support,we are hoping the Barnes bullets stablize and will give us great accuracy.

For what ever reason, the Barnes bullets tend to be very picky
in which barrels they shoot well in...

Since we have 1:8 twist barrels we should see excellent stabilization w/ the long/heavy bullets in 6.5 caliber.
 
Hello Fellas, I lot of you were asking about the Barnes 100gr. TTSX in the 6.5mm PCC...While Paul will be testing this bullet, he has yet to do so.

However, a lot of you guys already know that it has been a solid medium to large game bullet in other calibers...According to Barnes Engineers the
the 6.5mm 100gr. Barnes TTSX will reliably expand down to 1,800 fps. and my still expand well down to 1,550fps.

So I will give you guys all the available specs. of the Barnes 6.5mm 100gr. TTSX bullet, as well as the Ballistic Computer Modeling w/ various barrel
lengths in 6.5mm PCC...

Bullet Type/#: TTSX/26468
Bullet Length: 1.157" (Listed as 1.190", which is not correct)
Bullet Weight : 100 grs.
Bullet B/C: .360
Sec. Dens. : .205
Bullet Material: 100% Copper w/ Polymer Tip
Rounds per Box: 50
Price per Box: Approx. $35


Ok, w/ the 22" 6.5 PCC Bbl. it looks like this:

Velocity (FPS): 2,708 Energy (Ft.Lbs.): 1,630
All near Max. Pressure of 55,000 PSI. Using H322 Powder.

18" 6.5 PCC Bbl. :
Vel: 2,610 fps. Energy: 1,515 ft./lbs.

16" 6.5 PCC Bbl. :
Vel: 2,550 fps. Energy: 1,445 ft./lbs.

The best news being that the actual field results are giving us better velocity that what the Ballistic Computer is giving us thus far w/ most loads...
 
The Lapua 144gr. FMJBT came in today...w/ a Incredible .636 B/C WOW.

I will run some more Ballistic Modeling when I get back for the Lapua 144gr. bullets
in the 6.5 PCC .

OK, here is how its looks like w/ the Ballistic Modeling w/ the Lapua 144gr. FMJBT in the 6.5mm PCC w/ the following barrel lengths, using AA2495 powder (9.9% Compr.) at just under max. pressure of 55,000 PSI.

22" Bbl. 6.5 PCC :
Velocity: 2,285 fps.
Energy: 1,669 ft/lbs.

18" Bbl. 6.5 PCC:
Velocity: 2,208 fps.
Energy: 1,558 ft/lbs.

16" Bbl. 6.5 PCC:
Velocity: 2,162 fps.
Energy: 1,492 ft/lbs.

ETA: The Ballistic Computer Modeling shows Winchester 748 is slightly more efficient and gives slightly more velocity w/ no compression needed (100% Fill).Paul was correct the numbers are from the muzzle (15 feet).
