anybody using a 6.8 upper?

Popping an unsuspecting bear in the vital at 100 yards, I would use a 6.8 in a heartbeat. It may be  abit light on a bear running at you. That being said, I think it is a lot more lethal and capable cartridge than many realize.

Those 85 grain Barnes TSXs at 3000 fps are vicious when they hit meat and bone.


My 6.8 :

Benchmark will work, just dont know the recipe. It is faster than H322 so you may hit high pressure faster.

Here are some benchmark loads for the 110 vmax.

Looks like he is running tham at 28 gr and 50k. You could probably run it up to 28.5 if you have a sammi II or later chamber and a slow twist barrel.

As far as bug holes with the 6.8, I consider it mostly a waste of time unless you build the gun with match parts from the start. The 6.5G or a 6mmAR (6PPC basically) is a much more inherently accurate round.

Just the the way the barrel is fitted is not too inspiring although bedding the barrel helps.
Also you cant mag feed and dial into the lands with an AR15 unless you single feed them.

I have had about 8 different barrel/upper combos and none of them would shoot under 1/2-3/4"
Some better than others though.

That said, It seems like I have read that people got good accuracy with the 6.8 and H322 powder.
