I wouldn't say that DD barrel is anything to write home about.
Plus the BCM is chrome lined and hammer forged. The DD is just a plain old button rifled barrel and will probably have less than half the life of a chrome lined, hammer forged barrel. While the CHF is good for barrel life, it is detrimental to accuracy.
This isn't really an apples-to-apples comparison.
I'm not trying to be a dick or a BCM fanboy, just pointing out that these were made with different goals in mind.
With the right load it averaged 1.5moa for 3 groups of ten, with a lightweight barrel.
Our standards may be different.
ETA: When Molon tested the Noveske Skinny barrel (similar profile) his results varied from 1.6"-2.12" and averaged 1.8". That was for 8 10-shot groups, using his match hand loads, (which I guarantee are better than mine), and his test was shot from a bench.
So for the DD to average <1.6", and to have 2 of the 3 groups under 1.2" is pretty darn good.

Pardon me, but the OP didn't say the DD was CL.
In my mind, it should be shooting 1MOA or under to be worth writing home about.
Molon has a thread on about the Colt SOCOM. Only 1 of 3 groups exceeds an inch but it is still less than MOA (1.02"group while a MOA is 1.047"). That is worth bragging about.
Excuse me if I still vote "meh" on the DD.

Yes, both barrels are chrome lined.
Comparing a lightweight, chrome lined barrel to a SOCOM profiled barrel isn't exactly apples-to-apples. In fact, I don't know of any tests out there, that show multiple 10-shot groups out of a true lightweight profile barrel, that are sub-MOA.
However, I have a bit of a Mea Cupla moment here folks. I had somehow transposed some digits when I did my measurements of the DD barrel, using the Nosler handloads.
Here is the actual target, micrometer measuring outside-to-outside of the largest of the 3 groups:

That's not a 2.5" group. That's a 1.501" group. That means I totally ****ed the numbers. The average isn't 1.585", it's 1.251".
That's 1.251" for 3, 10-shot groups, shot prone, off a bipod on a concrete slab.

Thanks for posting your results. I've always had an Aimpoint PRO on my DDLW, but I'd love to slap a magnified optic on it just to see what our combined capabilities are at distance.
This thread, to me, demonstrates how effective a weapon the AR platform is as a weapon and instrument for combat. Anyone on the receiving end of any of those groups would not live to fight another day, that's for sure.
I appreciate the OP taking the time to conduct his tests and post the results, that was a lot of effort, so thanks.
