Which one... 224 Valkyrie or 6.5 Grendel? Login/Join 
Member

I am having a hard time deciding between the two. I have a nice AR15 lower that needs to get built. So which caliber? Want to build a precision gun for 600-800 yards with the occasional 1000 yard fun. Yes, I do reload and plan on for whatever caliber gun I pick up.

What say you?

.224 unless you really want an AR with a loooong barrel.

Had the same dilemma recently, I went with the Grendel, mainly because I plan on using it for deer hunting as well. The 6.5 is better for what I want to do.

Had I wanted something for just targets and long range fun I likely would have got the Valkyrie.

Thanks. I have been doing some reading and it seems the Valkyrie is a little more finicky when it comes to making a good accurate load. The Grendel seems to be a little easier to make accurate and sounds like it doesn’t beat up brass as much. Hhhhmmmmm.....

I produced the following chart to analyze various bullets and caliber in AR15 and AR10 platforms. I used a combination of actual data from my own rifles and best-guess data for others. Barrel lengths of 20" for the AR15s and 24" for the AR10s.



The Valkyrie flies noticeably flatter than the Grendel, and with a little less wind deflection. A good 223 bullet, such as the 73 ELDM, doesn't take all that much of a back seat to either at moderate distances.

I compete in team steel matches with a 20" barrel 223. Targets are regularly 500-650 yards, generally around 12" in size, and almost always in some level of wind. These are challenging conditions for consistent hits with ARs of any type. IMO target shooting at 800-1000 yards with an AR15 is more of lobbing bullets at big targets with high hopes than precision shooting. It can be done of course, but it's not a high percentage proposition with the 2 MOA-ish targets that I see in competition.

Without regard to your eventual caliber, if you're going to shoot at your stated distances, get a long barrel for velocity. Go with at least 20", but 22" to 24" is better. With the 22-24" barrels, consider an extended gas system -- one that's 1-2" longer than the normal rifle-length gas system.

Buy a top quality barrel -- JP, Wilson, Krieger, Bartein, or similar. Have a very good 'smith assemble it. Consider Craddock Precision on your short list, if you don't have anyone locally.

Grendel builds seem to have much less issues with barrels, chambers, and ammo. Valkyie builds seem more fickle. There are camps that feel Valkyrie 1:7 twists are good enough, others feel 1:6.5 is necessary for the heavy bullets.

If you shoot a lot, the Grendel barrel will have a lot longer useful life. Very little data about how long before a Grendel's throat is toast, but I suspect it will take 2-3 times as many rounds. I've seen webz reports that some Valkyrie barrels didn't make it past 2,000 rounds.

If you go with the Valkyrie, make sure you get a barrel with the SAAMI chamber and not a long chamber. Craddock is doing it right now. If I was buying now, I'd buy one of their current barrels.

and if you go with Grendel, make sure it's the type 2.

I went with a 20" Grendel build.

I went with an 18” Grendel, still in the evaluation stage.

I do very much like the 73 ELD in my 8 twist, 20" AR. I'm not sure of the velocity, but I think it's close to the 2800 on the chart. Weather, wind and other stuff has crimped the chrono time. On 400 yd steel, in nasty wind, the little .223 sure did shoot tight. Longer steel was more of a challenge due to 18mph+ full value wind that ended our fun. For me, the Grendel has just not sparked any joy. 24" barrels do make it shoot though.

BTW, Fritz always brings great info and data to the discussion. Much appreciated sir!

just paper .224

Anything else where you need impact force 6.5 Grendel. I hunt with my long range rife so 6.5 is where I went.

I hunt with a .224 and I have no problem taking down deer. Although I don't take shots over 200 yards due to the woods where I hunt.

Yep but, it sounds like you need some work to get there... long throats, Federal says 1:7 barrels just fine for long heavy bullets but, some research said 1:6.5, etc... seems like the 6.5 Grendel is a little less finicky to make shoot tight....
