A Grendel at Thunder Ranch
#1
I took my 22” Black Hole Weaponry rifle to Thunder Ranch over the weekend for their two-day Long Range Scoped AR class. As the name implies, the course is designed around using a scoped AR in a designated marksman style application engaging targets between 100-to-700-yards. My local range doesn't have any facilities for this. I’m limited to paper at 300 yards. This class would be my first chance to engage steel at a mid-ranges.

The weather was great for late March in the high desert of Lakeview, OR. Overnight temperatures were in the high 20’s with afternoons in the high 50's. Sunshine. Wind was mild both days.

Of course, most students had 5.56s with 16- or 18-inch barrels. Ammo ranged from 55 to 62 to 77 grains. Even though wind wasn't a major factor, I got to see the limitation of the 5.56 at 500, 600 and 700 yards, even at a 5400-foot elevation. Some students had to have their shots walked in at extended ranges. Other weapons systems (the barrel, ammo and shooter) just weren’t providing consistent hits beyond 4 or 5 hundred yards. Green tip and a rack barrel aren’t the combination you want for this class.

That wasn’t an issue for me. The Grendel was superb. There were some misses, but Doc would give a good wind call ("Favor left") and we'd have a hit. I’m an average shooter but the Grendel made me look good. I started day 2 with a cold bore, first shot hit at 700 yards. That was followed up later in the day with a 700-yard head shot. Dial, aim, press, hit. One of the staff came and asked me what I was shooting and said he'd never seen a Grendel in class before. It even caught the attention of Clint Smith who commented on the performance of my 'zip gun' (his term for any non-military caliber). High praise coming from him.

The student just to my right was shooting a 6mm ARC. It was a new, untested build using a Ballistic Advantage barrel and shooting factory ammo. He had nothing but problems with consistency. Shots would land left and then they'd land right. Then they’d be high. It was so bad I suggested he check his scope mount screws. He never did get it sorted out. I suspect a bad barrel or bad trigger pull.

And the Grendel was the heavy hitter in class. There’s a resettable target at 200 yards. You shoot the head, which falls and then shoot a plate to reset the head. When my classmates couldn't reset it 5.56 or 6mm ARC rounds, I was called upon to use the Grendel. It hit hard.

I want to point out that my system is pretty affordable. The barrel cost me $280 five years ago. It’s an overachiever for its price. My scope is a 1st gen PST 2.5-10x SFP. It cost around $600 when it was the new hotness 8 years ago. Its nothing fancy by current standards. However, the turrets are repeatable and the reticle is fine enough for precision work. With my reloads it’s a consistent 1 MOA performer. That’s all you need to do this type of shooting.

A big part of my success was having used the system (rifle, scope, ammo) for the last four years. I’m familiar with it and it’s been reliable. I was just able to perform with it. Joe (with the new 6mm ARC) came to class with a new barrel and new scope. The bugs weren’t worked out. It showed.

I not gonna lie; this wasn’t cheap. $1000 for two days on the range, plus ammo, travel food, incidentals. I thought long and hard about spending the money. But besides the 700-yard range, you also get an expert calling the wind. This gives you the best chance to perform well. It was the best way I could think to test my rifle and myself. The Grendel performs.

That's awesome! I really want to take a course like that once I get more familiar with my scope and reloads. Sounds like you have your systems pretty well sorted out. Were the people running 77gr in the 556 hitting consistently more frequently than people running 55gr?

Yes. Johnny, to my left, switched from 62gr green tip on day one to 77gr Sierra's on day two. A definite improvement.

bio,

Interesting.

Were those shooting 77gn using M262 factory or were they personal handloads?

What was the shooting position(s)? Bench/bags? Prone with sling or Bipod?

It was almost exclusively bipods from the prone. We did one run through the Challenging Terrain positions. They've added a phone booth (a what? ; )) and a truck bed since this video was made. I would have like to have run this a couple more times.

I can only speak to the shooter directly to my left. Those were handloads from another student in class. The increase in hits came mostly at 6 and 7 hundred yards. Thunder Ranch sits at 5400 feet so that helped with the ballistics.

I was surprised anyone would show up to run this class with SS109. My somewhat limited experience with it is it's a 3 moa load.

Neat post! Thanks for sharing.

I will say, this part right here is key. While I agree with everything you said about the Grendel shining, and I think it's the best-choice round for that application; the big one is you knew your kit. If someone really knew their .223 AR, and were running a 20" BBL with 77's, they'd be hitting that 700 yard target all-day long. But even with that, they wouldn't be hitting it nearly as hard as the Grendel does!

I'm kind of surprised people were showing up with 16" M4's and 55 ball.

It's my understanding that SS109 is specified at 4 MOA due to steel pin axial alignment within the projectile. I personally would never consider it for an accuracy event.

I've been working on learning the long range game for about a year with my creedmoor and when I get my load worked up on my grendel I plan on switching to it for some long range shooting since it will be my primary hunting rig. The first time someone get that delay of the rifle going off to the "ding" of the steel they're instantly hooked on getting farther and farther. Maybe I can justify a coarse soon

Very cool report. Thanks for sharing!

For the life of me, I don't know why a major bullet manufacturer doesn't take the 6.5mm 120-class into the 21st century by giving it one of the new hybrid nose ogives. Why do they keep offering the same old boring thing?

Attached is my Photoshopped example of a Berger 6.5mm 140gr with some bearing surface removed to reduce weight — nose and tail remain exactly the same. Simple, right?

High velocity and wicked BC, and would maximize the Grendel.

I agree...Spending $1K on a course with average ammo seems strange. But it might be that the person doesn't know or have reloading skills/equipment. You'd have to be a committed prepper to spend that much money to see how bulk available ammo shoots.

Watching that video you can tell he has said "Finger straight - Safety on" a thousand times LOL.

Hahaha it's hard enough to get hands on a .264 bullet 140 grains and under right now... but completely agree there's no reason we shouldn't be able to get a g1 bc within .020 of a .243 by tweaking core position and jacket thickness and shape

How much ammo did you bring, how much did you use?

They ask that you bring 500 rounds. I shot about 260. I'm not bragging when I say I think I shot less because I had mostly first round hits. Those with more follow up shots shot more of course.

I'll say again that Spencer "Doc" Clarke did a great job calling the wind for us. I did what he said and I never shot more than twice.

Ha! Love it. And hey, it's not a crime to brag. Go for it - you did good. You picked the right gear, and you knew how to run it. Brag away Smile

Well done Biodsl. Nice AAR (After Action Report).

Grendel's have been known to be performers up to and past 1k for a while. I ran mine at the monthly Sporting Rifle Match in Raton for the first two years I shot it, and my best score ever came from my 18". Farthest target is 885, and one stage the closest is 700.

Good data on your rifle and ammo, good dope, good skills and you can get your first round hits with just about anything if the equipment is sound.

Catchy sig line here.
