r/65Grendel

Having some Grendel issues. Light strikes and then most recently today some failure to extract. Disassembled bolt it was full of this shit. I’m assuming it’s primers. Had some lodged behind the extractor and gumming up the firing pin channel. I’ve been running a bunch of Nemo 120gr FMJ but also consistently shoot ELDM and haven’t been paying enough attention to the brass to blame it on an ammo yet. The cases I noticed today at the range did have like sharp metal poking out of the primer maybe pierced? Just curious what yall think. Running a faxon 18” barrel and BCG + faxon AGB and Huxwrx 762ti.

I’m in the process of going through the bin to build myself a 6.5 Grendel AR, and found that my 5/8-24 muzzle device is a bit short…?

Barrel is the Ballistic Advantage 18” Rifle Length Premium Series and I didn’t see anything in their documentation that states that they have anything special. The crush washer isn’t on in the picture but that’s just so the gap is more visible, it’s still got enough room for the crush washer to flip around when fully tightened. Any thoughts?

This video was at 600yds as we worked out. But my 14yo got his first hits at 1k with 123gr ELDMs. He got a real kick out of the 4.5 seconds it takes from the shot to the ring of the steel getting back to us.

Ready to run these bad boys out of my new SOLGW 13.9" - not sure when exactly SOLGW* discontinued this platform*, but I found 3 still available online. Skeptical, I contacted to verify SKU and new... sure enough, real deal!

Amped up to hammer some hogs!

Will be using my AGM Rattler v3 at about 77yrds

*edits for clarity

These were all shot with an 18" faxon match gunner barrel on an ar that I built. I think its excellent that s and b ammo groups so well. The first pic is hornady black. Which I always thought was the best but my rifle consistently groups s and b better. Is there a premium ammo line I should try that uses a bullet like the s and b uses?

I have tried 90 grain tnt. and frontier. they are not great.

What would you try if you knew this info? what is different about the s and b bullet that my rifle likes better? Ill tell you what I am going to buy a few 600 round cases of the s and b.

My ruger american groups the s and b better as well. Does anyone know what bullet they use? I am sure its nothing available commercially.

I'm just posting for discussion, my goal is consistent sub moa groups of 5 at 200 yards. I did hit a 10' gong at 560 yards last night on 2 out of 3 tries. I thought that was awesome. Definitely the furthest I have shot.

I think these are pretty cool and just want to show them they're Serbian and hopefully one day they can be imported into America in some fashion. Many people don't even know they exist, so I just want to post this here so people can get a heads up of that they even exist. It's a cool little internet artifact I thought so maybe somebody can start a little research on them.
