To get members on the same page and to ensure the results are uniform with other members attempting to make use of the load data being provided, I ask that all participating members list all pertinent information, to include: Case manufacturer, type of primer used, whether or not a crimp is used, barrel length and twist, and OAL measurement. Please note to all members and visitors viewing the thread, the load data being supplied is for reference only! Please follow proper reloading techniques and start with the lowest SAAMI recommended load and work your way up. I will do my best to determine the pros and cons of small vs large rifle primer cases but I have yet to see any smoking gun difference. The data provided in this thread will be for Type I chambers.

Alexander Arms has load data on their website.
I use 26.0 grains of VihtaVuori N530, AA brass, Remington 7.5 primers and 107 grain Sierra Match Kings seated @ 2.250". This load shoots 1/2" five shot groups at 100 from my 1/8 twist 18" AA barrel. It shoots 1.25" five shot groups at 100 from my 1/9 twist 24" AA barrel. The 142 SMK is too long for the small case capacity to drive it very fast. It takes up a bunch of room when seated to magazine length. |

Lyman 50 does not list bullets heaver than 129 grs.
Didn't see any of your listed powder in the data either. I've been loading with CFE-223. IMR-8208 XBR, and H-335 with the 123 gr A Max. We get a Grendel thread every now and then. If this one takes off I'll toggle it. |

I have the Grendel handbooks available here.
They are co-authored by our very own LRRPF52. They are fantastic resources. I'm an old handloader, but new to the Grendel, and these books were a major help. |

If I remember correctly, 2000MR is a relatively new powder and it was designed around the 77SMK and similar heavy bullets for the AR15. Because of that I would imagine that it would be an excellent candidate for the 107gr - 120gr SMK in Grendel. Don't get me wrong, I do like 8208XBR but it's no longer a powder that I can get at my local gun shop. I received a few pounds of Superformance from a friend and I scored 2000MR for $165, so I kind of cornered myself from buying anything new for a while, so I hope I didn't screw mysef up by doing that. |

I notice that my case OAL was within the spec but AFTER forming, I notice that my OAL shortened to 1.490". I hope that after a few firings, I can grow the length to proper SAAMI length but expect to see some kind of shrinkage when fire forming 7.62x39. |

Just adding a data point and bumping what I feel is an interesting thread.
Today I seated primers and loaded my fireforming loads into my 7.62x39 cases. I used Ramshot TAC and the start load in the Hornady manual for the 123gr SST bullet- 24gr. Should work for what I'm trying to do. Next time I'll use new cases and not a hodge podge of 1x fired 7.62x39 cases that I have on hand. |

I don't know if you have the problem I did when forming cases and having a flare at the mouth, which I normally trimmed off. Now, I just size and crimp if I'm still withing spec because I know the case will shrink when firing. There are several powders that I will now use to fire form 7.62 cases into Grendel but the best seems to be Titewad and Trailboss for the case volume. They might not fully form the shoulder but it's gentler on the case than even the start load in the Hornady book. After than, I can use whatever load I feel comfortable with and won't have hard extraction marks or case dents. |

This has become my favorite cartridge to load for.
It takes such little powder, like a 6 BR, but hits really hard on-target. Brass is available from: Lapua Hornady Nosler Norma Federal If you are fire-forming 7.62x39 for some reason, I would consider selling it and just getting Lapua or one of these others. Lapua brass has proven to be the most economical because of how many loads you will get, even without annealing. Since chamber pressure is relatively low compared to most modern centerfire rifle cartridges, you get a lot of brass life, even in a gasser. For me, my go-to powder right now is CFE223 under 120gr TSX, 123gr SST, 123gr AMAX, 129gr SST, and 129gr ABLR. I'm getting exceptional speed and accuracy with CFE, which is what I was looking for when I first got into the Grendel. To be honest, when I first took my Grendel out to test some loads with 123gr Scenar back in 2009, I was not impressed at all with how slow I was getting. I think I was using N140 first. Once I moved into 8208XBR and some other powders, it started to shine. I started with a 16" barrel/bolt combo from AA via site sponsor Midway. As Hornady factory ammo poured into the market, I found a great, affordable load that I could shoot without having to reload, and have been able to easily duplicate/exceed its performance with CFE223, and that has been vetted out to 1000yds on steel. I'll post some of my personal loads that I have tested. Gotta go take my girls out for daddy-daughter night now. |

My favorite load is Nosler 100's, N133, lap. brass and a mag primer. The partitions and the BT's both shoot the same for me. So, punch paper with the cheap BT's.
The old test load was 28 grains of TAC and a sierra 120 matchking. If the weapon does not shoot that reasonably well, there is likely an issue with the weapon. I never have any real success with Win748/BLC2. H335 shot well with stuff under 100 grains. Speer TNT 90's are another cheap plinking bullet. Its a flat based bullet that was great at 200 to 300 yards. |

85 grain Sierra Varmint and 100 grain varmint bullets are very accurate for me. I’ve even had very good accuracy with factory seconds purchased from the Sierra factory outlet store. I have used TAC with lighter bullets but really like A2230/Xterminator and H-335 with lighter bullets. I loaded 107 grain SMK with IMR 8208 XBR and got very good results. I also have shot quite a few 100 & 120 grain Nosler BT and try to buy blems or over runs.

Many 6.5G loads seem to have accuracy nodes near the max. So, work up, but kinda sorta anticipate the best loads near the top. In contrast, for me, Varget and Sierra 69's present a mid range node in the 24's and an upper node in the 25's.
With a Sierra 120 and TAC, the top is at/near 28.8. Ease up to it, but my best load is just that: 28.8. Bunch of us semi early adopters were working before some of these newer powders where available. Reloading data was basically the AA list with a couple or five loads for maybe ten bullets. At that time, there was some frustration with stuff over about 120 grains because the accuracy nodes seemed to be narrow, and the some of the powders like BLC2 tended to be temp. sensitive. 2520 was almost unavailable for periods of time. Meanwhile, some of the faster powders and lighter bullets were easier to find and get to shoot well. Nov. and Dec. 2008 and much of 2009 were some dark days for reloaders. Whole different world now with the Grendel reloading manuals. If you don't have them, buy them. Excellent collection of data. |

One bullet that seems accurate with any barrel is the 120 grain Sierra Match King. Another bullet that consistently shoots well is the 85 grain Sierra varmint. The 123 grain SMK, 123 grain Scenar and 123 grain Nosler CC have a higher BC than the 120 grain SMK but doesn’t really matter if your not going to shoot past 600 yards.
The 6.5 Grendel is an inherently accurate cartridge and it is not hard to find good accuracy with multiple bullets of various weights from 85-130 grains. I define good accuracy at consistent 1”-1.5” groups at 100 yards with at least 5 shot groups preferably ten shot groups. I’m usually the weak link in my guns accuracy. I generally shoot off a bipod with rear bag. I know my guns shooter better using a lead sled but I like the challenge of shooting off a bipod. |

What is the suggested primer for a 6.5 Grendel?
I will probably be using Hornady brass, which I understand uses a small rifle primer. I have some CCI #400 on hand. Do I need to pick up some small rifle magnum primers? I'll be working up loads with CFE223 and A2230. |

If your 6.5 Grendel is an AR-15 with floating firing pin I wouldn’t use the CCI 400 as use thin primer cups. I had pierced primers with Winchester small rifle primers in a 5.56 AR-15 because of the thin cups. I have used CCI 41 Miltary primers and CI 450 primers with good results in the 6.5 Grendel. Remington Magnum small rifle primers and Bench Rest BR4 small rifle primers get used in the 6.5 Grendel. I’ve never found any to buy but Wolf small rifle primers for AR-15 were popular a few years ago.
I’ve read large rifle primers all use thicker cups and I’ve had good results with Sellier & Bellot large rifle primers in fireformed 7.62X39 brass and PPU 6.5 Grendel brass. |

I've used CCI 400's in 223, never a problem if primer is seated correctly. (002 to .003 below flush)
In 6.5 Grendel I use Rem 7 1/2's as they are a match primer and work well. |

I've used CCI 400's, 450's, and 41's, S&B, WSmall Rifle, Fiochi, and Wolf.
Each of them, 100's and 100's of times. Never a pierced primer in three different 6.5 G's. In 5.56, I've used each of them 1000's of times. Again, no problems across 8 different AR's. |

I've done extensive load development for a shilen, criterion, and ARP barreled grendels.
With the 100 gr ballistic tips, I've gotten superb accuracy with 30.0 gr TAC and 32.0 gr BLC-2 and the bullet seated to 2.250". My rifles likes 27.7 gr AR Comp, 28.5 gr XBR-8208, and 31.2 gr CFE 223 with the 123 AMAX seated to 2.260" |

Does anyone have any load data on Hodgdon 414...? I’m trying it soon as the weather calms down a bit.
I just loaded up 5 rounds for each, 30.0, 30.5, 31.0 and 31.5. Using 123 Hornady SST’s with BR4 primers in Hornady brass with an over all length of 2.25. I pulled those number from Hornady’s book and the slowest powder they had listed of CFE223. I also plan to load some of the same bullets with 8208 XBR, charge weights will likely be 27.5, 28.0, 28,5 and 29.0. |

With the 6.5 Grendel 30-31 grain case capacity it is wise to only go up .3 grain (roughly 10% of case capacity). One other thing to be aware of when loading with IMR8208XBR it spikes quickly, most people stop at 28.5 grains or less with 120-123 grain bullets. IMR8208XBR and AR Comp are popular powders for the 6.5 Grendel and both are reported to be more temperature stable than powders like CFE223, Accurate 2520, Winchester 748 or BLC2.
I’ve never seen any load Data on H-414. My burn rate chart shows H-414 as being slower than H-380 and H-380 is slower than Varget. You can use Varget in the 6.5 Grendel but normally you can’t get enough Varget in the case to get desireable velocity with the 6.5 Grendel. H-414 is more suitable for 6.5 Creedmoor and I’ve seen data with H-414 in the 6.5 CM. |
