That sounds about right.

Per questions, I’ve added better picture of inlet as well as weight.

I shot my LMT 6.5 CM 20" at 100 and 300 yards today to re-zero. I just got the scope back from Nightforce, The parallax got out of whack internally somehow, they were pretty good about repairing it under warranty, but it did take 6 weeks.

Overall, I'm impressed with this rifle. Every group was sub MOA today, except the first cold bore shot on a very clean barrel (1.14"). The groups at 305 yards averaged 0.5 MOA (1.11", 1.87", 1.52"). I'm absolutely thrilled with that from a large frame gas gun, no malfunctions, gas perfectly, I really couldn't ask for much more from an AR10.

It would be interesting to shoot through a series of photo gates to determine at which range the velocity begins to meaningfully diverge for the 16, 14, 13, 12, and 9 twist barrels. This would allow for the user to balance the gains and costs of the faster twist for their use. Obviously LONG range will go with the faster twist but for shorter ranges it might not always be worth the finicky nature. For instance it seems unlikely that 50 yard BR guys will be making the switch.

That would be pretty cool. And I agree, the 50 yard BR guys only care about what was new 50 years ago, when most of them were in their 40s.

C’mon BR guys, I’m kidding.

Finally picked up my LS today thats going in the Miata.

6.0 L76 block bored 4.010
4.8 crank(destroked to basically a 327)
Wiseco +11.7cc dome forged pistons
Callies Compstar 6.250 h-beam 4340 rods
King and Durabond bearings
all ARP hardware
custom Cam-Motion cam

Heads are just stock LS3 821 heads that have been skimmed to clean them up. Have the factory 2 piece intake valve and stainless exhaust(or whatever the OE exhaust is). Getting BTR shaft rocker setup, .660 platinum springs w/titanium retainers. Stock LS3 intake manifold. Gen 5 Camaro exhaust manifolds.

Still need to get lifters(Johnson 2126LSR) and pushrods(manton 3/8 oil restricted).

Should be 11.25 compression with an .040 Cometic gasket.

No unfortunately we are Winchester at the moment, I’d say mid-September is the earliest before production starts rebooting.

When you reboot, will the stripped upper/arca handguard be available by itself?

Should be mostly broken in then. Also possible your lot of Varget is on the slow side or has a bit more humidity. Based on your test targets I'd just rock 31.6 gr at about 2800 fps, watch to see if it speeds up which might put it in the 31.9 velocity range. If you ever change lots of Varget recheck your speeds.
