6.5 Grendel Preferred Loads
1Shot Wrote:I have an 18" Oden barrel and the only factory ammo I have shot is 123 SST and it would average between 1 1/2 to 1 3/4" five shots at 100 yards. With certain handloads it shoots 1/2 MOA. It really likes 120 Sierra Pro Hunter, Hornady case, CCI 450, 28.5 IMR 8208 COAL 2.250 with a medium Lee Factory Crimp. It runs average 2540 fps. I have only had this rifle a little over 3 months and have not had the weather or time to try all the loads I want to try.


kpswihart Wrote:31 Grains of CFE, with CCI 450's at a COAL of 2.250 gave me an average of 2459 fps. Factory ammo averaged 2460 when measured. These loads, like factory, shoot under MOA when I do my part.

Sticks Wrote:This is not the norm. If you do a general search here on the SST, you will find more often than not, people can not get them to group under an inch, whereas the ELD Black ammo is the goto for accuracy.

I had heard good things about the Black ammo, that is why I bought 500 even before the gun was assembled. I was just glad I picked up a couple of different boxes at the gun store before heading to the range, I would have thought there was something wrong with the rifle. Does anyone make factory loads with Sierra's on top? I would hate to buy bullets too that don't shoot in this rifle.

Oh and if anyone in the Jacksonville area would like a good deal on some Black ammo let me know Smile.

Found that American Eagle makes a 120 Sierra topper, will pick up a box or 2 to try.

The American Eagle ammo has 120 Sierra MATCH KING not Pro Hunter bullets. I don't know of anyone who factory loads the 120 Pro Hunter. Good luck even finding 120 Pro Hunter bullets right now, seems everyone list them as OUT OF STOCK. Sierra must be just running Match King bullets right now because you can find them most any place but their Pro Hunter and Game King bullets have dried up. A few months ago I got a box of 130 Sierra Game Kings and did a preliminary powder work up with LVR in my BCA barrel rifle and found what I believe is going to be a good load. The load put five in just under 1 1/2" but was a good round shaped group. I had them loaded 10 thousands off the lands so I have some more loaded with that powder charge but 20 thousands off the lands to see if it tightens up. I was running low on the bullets and tried to find more and every place was OUT OF STOCK with many saying no back order. Yesterday I went into a gun shop in the town next to mine and BINGO they had two boxes. Notice I said they HAD two boxes. They came home with me. Now to get time to go to the range.

So went back out today with more Black and SSTs. Totally disappointed. Both shot 1.5 - 2 MOA. I will bring my rifle to my gunsmith next weekend and have him check everything out . I had two other people try and their results were consistent with mine. It's not even like there is a flier, just a round circle group, none touching. Maybe I just got a bad barrel.

Anyone shooting 129 SST out of a short barrel accurately? Hornady 123 anything sucks out of my 12 inch faxon match barrel. Tried 120 nosler with ok results but expensive.

I tested increasing charges of AR-Comp and XBR with the 123 ELD.

I also tested a couple of the loads I’d seen mentioned. I’m going to load more around the sweet spot. The bullet wanted to be going 2,475 fps yesterday. It was 55 degrees at the range.

123 ELD
Lapua/AA cases
CCI 450

Odin Works 20” barrel

Not a 129 hornady, but found an initial starting point for zeroing the 130 sierra TGK (gamechanger)

How do you like the TAC? I bought some to try, haven't gotten that far yet.
The TGK 130 is one I want to try.

Try letting your barrel cool off between shots, It closed my group up pretty good

Still looking for something better. These were out of a 12" PSA barrel. I did allow the barrel to cool between groups and still got fliers. Gonna change my scope for load development. The 1-4 is not cutting it at 100yds. Want to make sure it's the load and not me.

Think I'm gonna try BL-C2 and H4895 with the 130 gamechangers and 129 ABLR

Revbc, I look forward to seeing how those loads work for you.
I'll be happy when I can get out and try some loads, looks like winter may be relaxing its grip here in Wisconsin.

I have been experimenting with 130 grain ELDs and found a winner I think.

18 inch Larue UU

26.9 Grains 8208 XBR
130 ELD
Wischester SRP
Hornady Brass
Mag length

60 degrees Fahrenheit
300' elevation

Caldwell Ballistic Precision Chronograph G2 10 feet from muzzle.

10 shot AVG MV: 2278 fps
with an SD of 4.

Sub-moa 5 shot groups at 100 yards. Haven't pushed it farther yet on paper.


Load gets a little crunchy when Seating but nothing crazy. I actually went all the way up to 27.2 and can't see any pressure signs

fdbyrne78, did you get a reamer for your barrel? If you did, I would like to rent it. I have a 22" and a 18" Saturn barrels that need reaming. Thanks..Ken
