My daughter just turned 10 and wants to get out and go hunting with dad. So I want to set up a rifle so that my kids can use it. But a 7 mag is just too much and I don't really want to buy a kids rifle that they will grow out of in 5 years. So I started looking around and found that the AR platform is extremely diverse, and the grendel looks to be the best caliber for what I'm looking for. I will be able to use it for varmits. Because I have used the 7 mag on varmits and it doesn't leave much for the taxidermist to work with. I can also put a suppressor on it and the kick will be virtually nothing for the kids. So to answer your question small game javalina, deer, coyotes, bobcats so on.

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.
LR55 Sorry
~Thank you very much LR55 i found a potential problem with my android app, it seems if i dial in windage in solution mode then switch to table mode that the data doesn't change, their not locked together so when i went to table were it give more data including inches drop ect it must of been at about 4-5mph. I will contact developer

I am a new guy here and would like to know if getting out to 800+ with the Grendel using a 5x20 requires a 10 or 20moa mount? Or does it also depend on the scope used as well......
It will depend on both the scope & the mount. I shot to 1k with my ior valdada but it took all my adjustment plus all the reticle holdover to get there. I've since put a 20moa mount on. Should have plenty, now.
i have a vortex viper and with a 22 moa base i just made it to 1200 with 1.5 moa hold over.

Depends on the scope and the velocity. I would recommend a 20 MOA rail for most rifles. I shot at 1000 with my Nightforce NXT and had to hold 3-3.5 MOA above the bullseye with my 28" barrel.

Thank's for the info. Sounds like a 20moa mount will be the way to go for me......
if you prefere rings, bager ornadance has a nice 22 moa riser for around 85 dollars. Its what im using on my 24" grendel.

Exactly right. Anything beyond 600m says 260rem or 7mm WSM for me. I just don't feel like messing with big ass Gorillas.
Mike what powder are you planning to reload those 129s with? I've been using the 8280 with Hornadys 123s but haven't experimented much with other bullets. Thought about Remingtons 120 or Speers 120s (?)

JR I think the Grendel is an excellent caliber to start her with. There is the obvious question, did you start her with say a 22? Get her a Ruger 22 and she can learn all the important rules of trigger control and breathing first. OMG you use your 7 mm on varmints? You seriously must have too much money to spend and no flinching either! Too much gun for varmints! Get a Frendel and welcome to the family!
That's a bummer to hear. I like shot barrels 18 inchers

Like others have said- 500-600 is golden, beyond that you better be REALLY good a reading wind or have no wind at all. I tried to shoot 1k this weekend with a 10-15 mph 1/2 value wind and struggled to even get on target.. However I have made consistent hits on a 14"x16" plate at 1140 yds on a calm day.
According to my Exbal program, with the meteorological and environmental factors that I entered, my 123 grain Scenar doesn't go transonic until after 1300 yards. Sure I have to read wind, and use the right corrections to get a hit, but I have to do that with any other cartridge.
Of course, if my bullet was going 1500 FPS faster, I wouldn't have to correct as much for wind. However, my problem is usually not reading wind accurately enough over the entire distance of the bullet's flight. But whether I miss by 10 inches, or 20 inches at 1000 yards, a miss is still a miss.
I've shot the Grendel a lot at 600 yards and in my assessment it is a very good caliber for use at this range. For Mid Range I have shot at 300, 500, and 600 yards, at which distance it is a competitive caliber. However for Long range (700, 800, 900, and 1,000 yards) the caliber really starts to ask what can be done to help shore it up. For these ranges I have a .260, 6.5 Creedmoor, 6.5X68, .264 Win Mag and my real fire breathing Dragon, the 6.5 STW. In my opinion the best caliber at mid to long range is the 6.5 Creedmoor. It is a factory load, uses a proven bullet, powder an primer.
It could be argued that the 6.5x.284 is more capable and I agree it is but not at the expense of greater recoil and reduced barrel life, I would argue the 6.5 Creedmoor is a better compromise and that the 6.5 Grendel is just to anemic.

Gee Bob, I think you might be missing a 6.5 cartridge here or there!
I really like the 6.5x47, Creedmoor, and .260. I had about decided on the .260 as my next 6.5, and then you go and say you think the Creedmoor is the best! I thought that the performance of the 3 was essentially the same, but with the advantage to the .260 because of all the brass offerings, especially now that Lapua is making .260 brass.
Now you make me rethink everything!
I'll certainly agree that at distances past 600 yards the others have a significant advantage on the Grendel. I did shoot the Grendel at an F class match at 1000, and with switchy winds, I was the only one with any X's. The .308's, (mostly) that I was shooting against had more problems than I did shooting Hornady factory ammo. The other guys shooting in F Open had equipment problems, I think, and fell out at 1000. I missed winning the stage because one of the .308 shooters saw a wind change I missed and had one more 10 than I did, but he had no X's. All the F guys were in one class because there weren't enough to make seperate classes. My goal is always to shoot with the .308 guys score wise when I shoot the Grendel, since that is what it actually stacks up against, even though I have to classify it in Open.

I agree about the distance when you push past 600, it makes more sense for the shooter who has a .308-based case necked down to .264" to load up and shoot that, rather than the Grendel if we're talking out to 700 and further.
There are more factory loads for the .260 Rem coming on line, so I'm not sure that the Creedmoor really commands an advantage there, but Hornady was smart to fully back the cartridge and publish the load data on the boxes so the hand-loader could duplicate.
The Creedmoor is Hornady's 30 TC necked down, which gives me the impression of "We have a 6.5 too!" more than anything, and Remington has totally dropped the ball on not supporting the .260 Rem while there is so much market demand for it now.
I chose .260 Rem for the brass availability, even though the Lapua impresses me the most with its ability to deal with insane pressures, and deliver extreme accuracy at high pressures, but one source of brass and very high-priced brass turned me in favor of the .260 Rem.
I know that Zak Smith is shooting .260 Rem after doing his extensive testing on all three of these .308 case-based 6.5's, and many bolt gun guys are getting 150fps faster using RL17 in the .260 Rem.
For a long-range hunting bolt gun, I have been thinking about the .264 Win Mag more and more, with early childhood memories revived of me shooting through 2 1/2 ton Army truck axles with it, and watching the axle spin head over heel violently, then witnessing the through-and-through hole it put in said axle like it was a plasma ray gun. With a melonited barrel, it would be a longer throat life laser.

Hodgdon 4831 was about the best available when my uncle used his in the late '50s and the '60s.
Bill, the .260 is a great caliber, the creedmoor is better, but by only a small margine, driven by the shoulder angle and less tapered case body. It is interesting that the AMU went with the .260 and Lapua responded with Laupua brass. However, Emil Praslick stated that the reason he chose it was to have a turn key solution with the Tubb 2K replacing only the barrel with their preferred barrel. He would not tell me the barrel manufacture but based on other conversations I assume it is a Krieger. I have a Snieder Polygonal and a Wilson six grove in the 6.5 Creedmoor. In my opinion it will give better barrel life, equal to better accuracy compared to the .260 and at less pressures than the 6.5x47.
By the way, I'm not sure what the Lapua brass offers that the Hornady does not in this class of case capacity, I'm only on my fourth loading of Hornady Brass but have so far lost none to loose primer pockets or case neck splits or head seperations.
I have over one thousand 6.5 Creedmoor cases some driven hard, and some with light loads so it will be a while before I understand the tradeoffs. At this point I would conclude the Hornady is a bettr life cycle value than the Lapua brass but I'm not yet sure of this.
Bob
No way will Hornady brass out-last Lapua. Do you think the Creedmoor will give longer barrel life than .260 Rem based on the shoulder angle torching the .260 more? I wonder how Ackleying the .260 Rem would help with that. What projected barrel lives are we talking about, anyway? I think barrel steel quality will be a big factor in barrel life more than the chambering between the two. Some guys have gotten 4600 rounds out of the .260 Rem for accuracy. I think we're looking at 3500-5000 rounds of accuracy life, depending on steel quality and how the gun is run with regard to hotter loads.
