Allot of other variables. For my rifle, because no to chambers, barrels, brass or bullet construction are alike, Benchmark powder for accuracy and Power pro varmint for velocity became my go to powders for mid size game hunting.
Sierra TGK Gamechanger 130gr Bullets with H335 highest velocity at lowest pressures with best groups ever. Yik yaking about powders without the data to show made no sense, they are all good powders its how they perform with a 6.5 bullet shoved in a 7.62x39 case that counts.
What's the barrel length in your testing or do the powders tend to run good in all barrel lengths??? Also are you shooting in the AR platform or bolt gun??? I've been wanting to get a bolt gun in 6.5 Grendel because I've heard you can get a lot more out of the cartridge but I have 2 AR15s built an 18" for hunting and a 24" for plinking at long range. The 18" is the one I'm having a hard time getting the velocity I want for a 120gr Barnes TTSX.
. *In a custom builds, which is what most people are doing today, the jump you speak of should not exceed more then three thousandths of an inch.* *Secondly, the length of the barrel is another big factor, the longer - the more time it has for a complete burn, which builds higher pressures, producing greater velocities with much better accuracy.* *Just saying.*
Lone Puma unless you are using a custom chamber reamer, the jump to lands on a SAAMI 6.5 Grendel reamer is around .125", on a 264LBC chambered barrel, its right at .100", to get a jump of .003" would require either a long seated bullet, or a custom reamed chamber using a custom reamer.

Good choices for Grendel. Might just be my barrel but i could never get CFE to shoot well in mine.
Great video a lot of good info. I am having great accuracy with H-335 and 120ELD loaded at 25.3 grain. I may try the AR comp to see what happens.
Thanks for the info. Toadley mentioned you. I plan on trying Hornady 120 eldm with ar-comp, CCI 400 primer out of a 24 inch barrel. Ar-15 platform.
H335 26.5 grains 140grain bullets sst or eld is my go to. H335 is military powder i also run the h335 in my .223 55grn loads same 26.5grn load
Man, are you the guy on Modern Sporting Rifle/Grendel II/Large Frame AR groups?
Does anyone have start grains for Grendel ?AR-Comp , 123sst
405 match primer components. Any help!
Speer shows 22.7-25.3
Few other videos show higher.

I shoot 18in 20 and 22in AR15s
26.5 grns h335 140 sst
Do you mead Free Bore?
