Ooooooh boy. He is good, and apparently smarter than the rest of us, especially me.
I had a rocky start with this cartridge but thankfully persevered and have been rewarded with some very accurate and effective loads.
On paper it looked great for a cartridge that would, inside of 500yds, be far and away more effective than the 5.56 but I bet you I burned theough 1k different bullet weights and styles, different powders by the dozen and jist couldnt get it nailed down. I haunted the 6 8 forum and was using all the right components and while Ive only been reloading maybe 7 years or so I think I have the basics down pretty good. I was doing everything they were doing and using what they were using except for one thing, my COAL's. I was sticking to charges and COAL's publoshed by the various manufacturers. I really had no idea that overall lengths, and the correspondingly higher charges that permitted, could make such a difference in the overall performance of the cartridge but it sure has.
Another big draw for me was not only its performance advantage but the fact that all of it was built out on a standard sized AR frame. All I needed was a bolt, barrel and magazines. Granted only a few mag manufacturers make them that will allow loading out to 2.295" (PRI) or 2.3" (ASC). I can get the Hornady 110gr bthp screamin out of a 16" barrel at 2630fps with a
stiff charge of A2200.
Sure, the there are other cartridges out now that best the 6.8spc but try stocking up on 6mmARC brass now and see how far you get. I didnt get far. Plus I already had a lot of the more potent 6.8 powders, primers and brass was still available when I got into it so I bought in bulk.
Anyone else shoot the 6.8?
