Quote HistoryQuoted: I’m no HSLD operator but what I do know is I have close to 1K suppressed rounds down the tube on my 6.5 rig with zero stoppages, FTF, FTE, whatever else you can think of. Home built 6.5 Aero upper and lower, BA 12.5” barrel, SiCo Hybrid. I can’t remember what spring and buffer I installed. My shooting with this gun is primarily killing hogs at night. Having said that, I’ve done more than a few “just for fun” mag dumps with both ELDM and Wolf steel with no issues. I have issues with probably 20% of my Grendel mags. Absolutely love the caliber. Mags suck |

Just for fun, someone with a 17 round E Lander that doesn’t run, IM me and I’ll send you one of mine that does. You send me your faulty one and we’ll see what happens.
(This isn’t a “call out”, I’m just curious.) |

And prove what? People ask if there's reliability issues with grendel mags. 7 out of 10 people say mags suck. So do you just go into it hoping the stars align and you luck out? I feel like it's pretty safe to say the odds of having mag issues is high. Like higher than giraffe pussy high. |

Out of 3 different 12" Grendels using 2 different types of barrels and 4 different types of magazines, none of us have had any malfunctions.
All have been run suppressed with 3 different cans. Mine has a Faxon 12", TBAC Ultra 5 30 Cal. and I've shot it with both the Maxim PDW brace with tiny buffer and stiff recoil spring, as well as standard carbine buffer/spring/RET with SBA3. The other has a Faxon 12", TBAC Ultra 7 30 with Maxim PDW brace/ tiny buffer/stiff spring. The other has a PF Bartlein, an OSS with Hk PDW stock kit and buffer. Shoots bug holes at 100yds and sub-MOA out to 925yds. Mags include CPD old, CPD new exaggerated curve, Elanders, and ASC. Ammo includes everything from 90gr TNT Federal, to 107gr SMK/8208XBR hand loads, to 120gr Federal Match, to 123gr SST, 123gr AG, 123gr ELD-M, 123gr SMK, 123gr Scenar, and 129gr ABLR. |

Ok, after much ruminations, questions, and ponderings, my Grendel is done. The hardest part was finding a 1 inch mount with a 20 MOA cant. I seriously thought it would be easier.
BA 20 inch barrel with a geissle ssa-e trigger. It liked the 123 hornadys better than the 120 fusions which is the exact opposite of what my buddy’s rifle likes. Best 5 round group at 100 is a little over an inch. I was hoping for better but all things being equal I’m still satisfied with it. My son and I are going to hang out at GA Precision’s range this weekend so hopefully we can tune it up and get dope to 1K. Best 123 group:

I have yet to see a SAAMI chamber in a quality pipe that doesn't shoot amazingly well, some rivaling most of the higher-end bolt guns I've seen. To be honest though, a barrel that will group 1.5 MOA is fine for ringing 2 MOA steel out to 1000yds. I personally get a kick out of rapid-firing a string onto steel at distance with very small groups that simply wouldn't be possible with other rifles that have more recoil and muzzle blast. |

Really, for the money I've got into it I can't complain. I set out to build an inexpensive, light rifle so my son can tag along with me to sniper matches and that the whole family can use as a deer rifle. I think I've accomplished that. Even the 120 Fusions group well enough for a deer, and I think our 1K targets hover around 3 or 4 MOA so he'll be fine. I'll do some load development for it and probably tighten those groups a little that way. Sierra should have their 123 SMKs in their seconds bin by now so I'll grab a couple pounds the next time I pass through Sedalia. Speaking of which, what's a good load for the 123s? Anyone know what replicates Hornady Black's load? |

I'm trying to scope my Larue UU 6.5 Grendel on a budget. Trouble is I'm looking for a scope and reticle that'll do it all. Precision, hunting, lightweight, not too big, yet still rugged blah blah blah. It's a do it all rife cartridge it needs a do it all scope. That scope is probably either the Nightforce 2.5-10 NSX, or the NX8 2.5-20, or Leupold Mark 5 or 6. None of which are currently in my budget. I'm trying to keep it in the $500-700 range, and I'm fine with pre-owned.
I've narrowed it down to the Burris XTR II 2-10x42 Mil, and the Athlon Ares BTR 2.5-15x50. Don't love the Vortex 3-15, or the Burris 3-15. Anything else I'm missing? What would you recommend between the Burris and the Athlon? Thanks for any thoughts... |

Truth is, I probably just need to choose whatever and put something on the rifle until I can afford what I want to put there. I’ve had a Leupold vxr patrol, vortex 3-15 and Burris 3-15. I wanted more mag range and higher precision than the Leupold offered, less size, and cluttered reticle than the Vortex 3-15 and less size and weight than the Burris 3-15. When push comes to shove I want a mil based reticle that leans more toward precision and less toward hunting which rules out the Vortex razor hd 2-10. There just really isn’t much of anything in my current price range. 
ETA: I have the 18” barrel and want to see how far I can stretch it out, but don’t want an optic so big I can’t carry the beast. |

Ok, fresh back from the range after trying a couple more loads for the Grendel. But unfortunately, I couldn’t get the groups tightened up.
The 123 BTHP Black was all over the place. It was more of a pattern than a group. Here’s the best 5 out of it: 
The 123 SST wasn’t bad and wasn’t awesome. 
And then I did another group of the 123 ELD just to make sure I was being consistent in my shooting, and it grouped about how I expected. 
I guess the good news is that now I’ve got enough brass to start load development on this thing. |

I mainly shoot Factory Hornady 123 SST ammo right now through my 16” AA barreled upper. Will be using this upper for deer and hogs out to a possible 200 yards max with a SDN6 and possibly going to experiment with the new Sightmark Wraith. |
