The 6.8 SPC II, Best all around AR15 cartridge.
Defensive and Hunting the 2 largest sectors
The 6.8 SPC is the fastest growing and #1 choice for hunting deer and hogs with an AR15.
Using factory ammo the 6.8 is apx 100fp faster than the Grendel using the same weight bullet and same length barrel. Out to 175 yards the 6.8 has more energy with 110 and 120gr loads. A 16" 6.8 loaded with factory Hornady 120gr SSTs has enough velocity to expand and energy to take deer and hogs at 400yds. The Grendel horde likes to say the 6.8 is a short range hunting round and the Grendel is long range...BS. Load a 130gr Berger Classic Hunter (BC .497), 130 Speer or Sierra BT in the 6.8 and it will push it to the same velocity as a 123gr 6.5 Grendel. The BCs are very close so the drop and drift will be very close way past ethical hunting distances and the 6.8 bullets actually expand as designed.
There are defensive bullets like the 90gr Gold Dot, and several fmjs. There are bonded hunting bullets like the 100 and 110 Accubond, premium solid copper bullets Barnes 85 TSX, 95TTSX, 110 TSX, Cavity Back 100 and 120 MKZ and Hornady 100 GMX.
The 6.8 mags feed better, metal and Magpul SIX8 mags. The bolts and extractors are stronger and more durable than Grendel based cartridges.
6.8 performance on hogs- VIDEO LINK
The 270 MSR is a powerful wildcat based on the 6mm Dasher case, H20 capacity is apx 42gr.
It is capable of propelling the wide range of 130gr bullets to 2800fps out of a 20" barrel. 130gr bullets with a BC of .500 to 2800fps. That is 300fps faster than a Grendel can push a 130gr bullet out of the same length barrel. The new Sierra 140gr GC with a BC of .508 or the 140 Berger Classic Hunter (BC .528)will hit 2700fps. It is one of the most powerful AR15 cartridges made. It would be good for deer at longer ranges, Mule deer, Elk.
AR Performance(ARP) as an online retailer is committed to providing the best practical high performance parts for the AR15 platform at a decent price( we cut out the middle man) The high performance "AR match grade" 5R barrels we produce were ahead of their time in 2008. Many are just now copying the barrels we produced in 2008 while I have designed and moved on to a higher performance 3R barrel. The new 3R barrels create 40% less engraving force and bullet deformation for handloaders wanting to push the envelope.
Our barrels are less expensive because I choose not to place as much markup on the barrels and sell more of them. Our barrels are easily sub MOA and with good hand loads they can be 1/2 MOA.
Better exterior ballistics, terminal performance, accuracy, velocity and long life are all possible with finely tuned chambers and high performance hybrid 5R and 3R rifling in Melonite treated 4150 CMV barrels.
TAC 6, 30 Herrett, 5.56x42, 308, 270 MSR, 270-08, barrels are all on the Misc. page
Due to the poor performance on game we do not offer any 300 Blackout barrels.
