Grendel at extended ranges?

[LRS_Ranger]

I'm interested in seeing what kind of performance I can expect at extended ranges.. What's the furthest you have taken the Grendel, and with what load? I'll be heading east of the mountains this summer, and I want to see how far I can shoot with it... planning on loading 123 scenars hot. We shall see...

[Drifter]

Furthest for me so far is 600 yards. Not much of a challenge using factory AA 123gr Scenars.

LRSR:

Tried it at 1K and it didn't perform. Have shot it on paper at 600 and it did fine as long as the winds were not real tricky. Shot it on a field fire range a couple of weeks ago to 700 and it did fine on sils. Just had to keep a real good eye on the winds. However my barrel is 26 inches and if yours is less you will have to pay even more attention to the winds.

Took it to 1000 yds on a steel silohuette for the first time this weekend. Load was a 29.7 gr of AA2520 under a 123 amax. The load chrony's at 2650fps out of a 24" .264 BHW barrel.

It was the first time for me to hit 1k with my own rifle and once I got on target it was 5 for 7 with the 2 misses having good height but missing left and right of the neck. I was aiming high to try to knock the larue over but it would just teeter.

The verticle spread was about 5-6" and the horizontal spread more like a foot. 13 mph and I don't know a thing about judging it, so I just kept holding a little more until I got on target.

600m. Wind is always the 800 pound Gorilla in the room.

[student28]

Prob a good 1.75 foot of windage at that distance with a sustained 13mph

Taken it to 1000 a lot. It does well unless the wind kicks up. I shoot 123 Scenars generally. I've even shot the Hornady factory ammo to 800. I wouldn't hunt long range with it but it sure is a blast to shoot. I've got a 6.5-284 for when I get serious about long range though. You can click my signature for some videos of the Grendel and others at extended ranges.

I wonder what the azimuth of his shots were as well.

I'm just working up some loads, but I shot mine this week at 600 yd and had a 4 1/2 in group. Heading to SD this week to shoot PD's, and am taking the Grendel along to try some longer ranges,if the wind isn't too bad.

I have shot my 20" Grendel to 1000 yards a number of times.
Actually utilized it for one of the Snipers Hide Cup matches down at Rifles Only in Texas a couple of years ago.
The guy laying next to me was using a 308 bolt rifle and I really felt bad about kicking brass his direction but the Grendel did just as good as the 308.
I put in a 15 mph correction as I thought the breeze was a bit over 20 mph but not at a full value.
First shot missed the Larue plate to the right a bit less than half a mil so I held left 1/2 mil and sent three rounds for hits.
The fifth round missed just a hair left because I should have increased my hold-off as the breeze was increasing.

Personally, I consider both the Grendel and a 308 to be 800 yard rounds. People utilize both past 800 but my personal confidence level is much higher if I am at 800 or colser.

I shot my 16in at Badlands Tactical a couple weekends ago. Wolf 120 MPT's to 700 had no problem hittin the steel. I will post my elev & wind correction when I dig out my logbook. I wanted to shoot 1k but spent to much ammo on the UKD ranges.

[Rootshot]

500m (550 yards) on steel silhouettes has been the longest so far. Accuracy is not a problem, but the Grendel fails to have enough kinetic energy to knock over the heavy steel ram silhouettes at that range. You see the impact, you hear the "ping", but the target stay up about 60% of the time. This was with factory Hornady 123 AMAX rounds.

Got rained out in SD, so no Grendel shooting and no PD's. Will try again.

[elfego baca]

So far my limits with the Grendel have been with the scope i have - a Burris 6x20 with Ballistic mil dot.

Maximum adjustment peaks out at about 676 yards.

I had the same with 123 A-Max. I tried the Wolf 120 MPT it did a better on the steel, but was not as accurate as the Hornady. I going to load Hornady's 129 Interlock and the 129 SST bullets this winter and try them on steel.

Shot at 800yd this week. First round hits with 123 scenars. Dialed in 25.8 MOA to get there.

Until that day,

My data with 123gr amax @ 2650 fps and 13 mph wind @ 1000 yards shows 3 feet plus drift at full value.

I'm new to the AR platform and the 6.5. I plan on purchasing or building a hunting rifle in the 6.5 grendel. I live in southern AZ and most any hunting is long range. I have done long range shooting with my bolt action 7mm. When it comes to cleaning and cooling down the rifle I currently will do 5 shots then run a cloth down the barrel and wait about 15 mins or so. The AR is designed to withstand many rounds, heat etc. For your long range shots do you clean the barrel after x shots or do you need wait for the barrel to cool for any length of time? Also what length of barrel do you recommend? I have spoken with local gunsmiths that do not recommend a barrel longer than 20", due to the barrel weight being too much for the receiver, and complications. However, I have always been taught that longer barrels equals better accuracy. What do you think?

Shooter:

Need to re-look that one. More like 130 plus inches given you can get that type of velocity from that bullet. That comes to 12 feet.

First off...welcome. 7mm is clearly more appropriate for long-range hunting, if we're talking 500 yds and further, especially with the Berger hunting VLD's. The Grendel has been used to hunt Elk out to 405 yds by Mark LaRue up in Wyoming, and makes a great little rifle to carry and hunt deer or medium game with. The longer, heavy barreled rigs are fine for varmints and some distance work, but a Grendel behaves more like a .308 Win as far as trajectory is concerned. A 7mm will smoke a .308, especially if we're talking magnums.

Barrels: Different quality in steel and workmanship will determine how well they hold up to heat and foul. Shorter barrels of equal diameter are inherently more accurate, due to increased resistance to barrel whip, but long heavy pipes resist negative shooter input better, so practical accuracy favors weight. Long barrels of course allow more velocity to be squeezed out of a cartridge and powder charge.

What exactly are you looking to do? What ranges do you hunt/plan to hunt at, and what type of game? Check the hunting threads as well. Again, welcome.
