Interesting. 90% of the time I use E Landers in this config and have zero problems, 100% suppressed and usually dirty. I do clean them from time to time but more from my experience with other calibers.
Your internal dimensions might be too constrained with them.
Anyone else tried this 5/16 round mag from Brenton. Will go to 2.3 OAL, though I might have a concern about recoil induced bullet pushback. More, after some testing. Insert limits you to 5 rounds, they say 16-I’d prefer to hold it to 15, with limiter removed.
There are multiple technology paths being developed parallel to the internal ballistics, so it’s a lot more than just slinging projectiles at 3050fps from an 8.5” PDW.
I’ve been using C-Products Duramags that are for 7.62x39 to supplement my Elanders. The 20-round mags work great.
Interesting. I cant get past 3-4rds before feeding issues with Elanders or ASC in my 18" Lilja/Mega billet upper. Duramag feeds without issue.
Well they show for sale on the Geissele website so perhaps there was a mistake, or maybe I need to stock up on a few before they are all gone.
At $100 a mag, be my guest. Ill stick with the poor approved duramag. hahaha
I have a 11” carbine gas barrel that is reliable. No function issues, but it is very finicky with loads- and shoots Hornady Black at about 3 moa. And the 1 hand load that shot well is SLOW! I moved to a 12.5” mid length that hammers. No, I don’t think my issues with the shorter barrel are gas length related. I wouldn’t be too concerned with going short.
I have a 10.5” CLGS 6.5 Grendel Criterion pipe from Precision Firearms but I haven’t focused on it yet. I’m kind of skipping to 8.5” Criterion from PF.
I feel like I’ve been trying to break Grendel bolt lugs for 15 years now. What am I doing wrong guys!!!!
No idea, maybe just do whatever the people with broken bolts do? The under cut lug on my AA bolt broke off.
No. Because I don't shoot 7.62x51mm in 308W chambers. That shit is dangerous.
107gr TMK works as a dual-purpose bullet. Sierra made the 105gr Blitzking as well.
Is blitzking rapid expanding and fragmenting or more controlled?
I plan to shoot a doe with a 100gr ELD-VT and see how it does. These shoot really well in my ARP and Rainier Match barrels. I plan to move one of my thermals from a 5.56 over to a Grendel this year for coyotes after deer season ends.
Hornady is a marketing machine. In the last few years I’ve seen more and more niche ar ammo for sale in stores. Even the ACE hardware stores here are stocking 6.8spc, 22&6ARC, 22 Valkyrie, and 6.5 Grendel.
From Sierra’s description, it sounds like a varmint bullet, but the lighter varmint bullets in Grendel demonstrate controlled expansion in medium game because they aren’t hitting as fast, unless you spit them out from a 22”-28” barrel at 2900-3220fps.
From the hunting perspective, it’s kinda like someone took the popularity of the Rem 700 action and performance of .30-30 and .243 Winchester, put it all in a semi-automatic blender, and created a new market that is dramatically-different than grandpa’s M16 from Vietnam.
