Does anyone have any information on loading the 6.5 grendel with Hornady 120 GMX # 26110 ? I did a search on ammo guide and found nothing useful.

Here's you some QL results. Please remember this is NOT published data, but it will give you some kind of idea what powders you might try and what results you might expect. Guidelines...


Code:
Cartridge          : 6.5 Grendel  (SAAMI)
Bullet             : .264, 120, Hornady GMX 26110
Useable Case Capaci: 29.961 grain H2O = 1.945 cm³
Cartridge O.A.L. L6: 2.260 inch = 57.40 mm
Barrel Length      : 20.0 inch = 508.0 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 52000 psi, or 358 MPa
or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

51 loads produced a Loading Ratio below user-defined minimum of 86%. These powders have been skipped.

Hornady's 9th Edition shows the #26110 GMX along with the 120 A-Max and 123 A-Max on page 286. Not near as many different powders as above, but TAC, Varget, RL-15, 748 and CFE-223 are there, with CFE-223 showing the most velocity. I believe the Hornady data is on their web site-

There is probably more Grendel data at Ammoguide.com than any other source over 600 loads and growing. Data from powder manfuactures, Alexander Arms and the writers of the 6,5 Grendel load books.

I haven't loaded the GMX but it is a popular bullet in the Grendel and available in loads from Precision Firearms.

I have been using Ammo guide and the second edition book from Alexander arms for data on 129 gr SST and 129gr. Nosler bullets. My gun is not liking the Nosler/CFE 223 combination. SST /CFE 223 is better but not good enough to keep as the all round load.

Mine is liking the Nosler LRAB 129gr and CFE. 30.3 gr CFE223 seated for length of 2.27 inches with CCI 450 primers. Same load that I settled on for the 130gr Berger Hybrids.

Not sure if it is the thinner jackets and little difference in bearing surface but max loads seem to be higher with the SST than with the Berger Hybrids or Nosler LRAB bullets.

Look at the percentage of propellant burned for CFE loaded at 52000 psi and consider kmon's load. I think it's a safe bet that 30.3 grains under a 129 will turn in a lot more pressure than 52000 psi. In fact, I'll just run QL on kmon's load:

Code:
Cartridge          : 6.5 Grendel  (SAAMI)
Bullet             : .264, 129, Nosler AccuBond LR 58943
Useable Case Capaci: 29.619 grain H2O = 1.923 cm³
Cartridge O.A.L. L6: 2.260 inch = 57.40 mm
Barrel Length      : 20.0 inch = 508.0 mm

Results caused by ± 10% powder lot-to-lot burning rate variation using nominal charge
Data for burning rate increased by 10% relative to nominal value:
+Ba    100    30.30   2646    2005   69305   7969    100.0    0.996  !DANGEROUS LOAD-DO NOT USE!
Data for burning rate decreased by 10% relative to nominal value:

So, at 30.3 grains we're a little over 57000 psi. Remember what the nature of progressive burning powders is. So here's QL telling us that kmon's load is burning 98% of the powder. I'd venture a guess that a load that burns 98% of its powder charge will be much closer to that ratio on a shot-to-shot basis than a load that burns 95% of its charge.

Not sure if it is the thinner jackets and little difference in bearing surface but max loads seem to be higher with the SST than with the Berger Hybrids or Nosler LRAB bullets.


30.3 gr good to know, I did a ladder test and decided that 29.8 of CFE 223 was what I needed. I took it to the range today and was very disappointed. But the good news is I have plenty of Noslers left so I can bump it up and try again.

I'm running a Alexander Arms upper 1:8 and 24 inches.

I'm also going to try some Sierra 85 gr HP when I get a little time.

River Rider- Just refreshed and got your info. I did not get any pressure signs at 29.8 but I didn't get better than 2 MOA on accuracy. Now I,m thinking i should stay with a lighter bullet.

I thought max pressure was around 58k

SAAMI MAX pressure is 52000psi for the Grendel. That in part is how good brass lasts so long and barrel life is very good with the Grendel. That limit is from not wanting to stretch the diameter of the barrel at the chamber with the limits of the AR-15 if I recall what Bill Alexander said about pressures one day.

In a bolt action there are lots of guys taking it to 58 to 60000psi. Not a recommended practice in the mini actions but in a 700, Sako or Savage Grendel should not be a problem.

I fully agree with that. The problem is, I think, that many powders just won't operate well until you push them up near 60000 psi. When you're consuming 100%, it doesn't get any better. I think a "one or two percent unburned" prediction is not too significant, but when the unburned portion begins to approach five or ten percent then consistency will be out the window.

IMR3031 caught my attention in some of the results I posted. AR Comp also.
