I'm wondering if anyone has any load data for h322 in any of the 6mm 6.8spc variants? Charge weight, bullet weight, velocity, barrel length and which variant your shooting would be helpful!
 
Just about the only powder Ive not tested in my 6x6.8, yet.
Going to run a test my next day off with it behind 55g varmageddons.
 
I did with 65g vmax in my 6x6.8 BHW 22" ar. Federal brass cci450 30.5-31 I had 3400-3475fps. I can't remember what it grouped like I'll have to revisit this again.

That's some good velocity. I can't even get the 58s above 3400 with 8208.
 
I run h322 pushing 70 or 75gr sierra HP's but I can't remember what the charge weight is and what the velocity is. It is a 6mmWOA with a 22in barrel. I will check later 2nite and let you know.
 
I just pick my poison pill and start with the top 6 PPC laod data and move up to the lower 6 BR stuff. It works for me every time.

I have exactly ONE load with H322 out of about 100. H322 27.7 grains, Hornady 87 grain HPBT, 2.295 COL 20" tube showed me 2934 with right on MOA. That was showing as MAX in my data sheet. Not bad on the speed. That was one of those whim choices I tried.

I'm not hardly past 3400 in a 22" barrel with 31.5gr of 8208
 
I know I'm not eithor so I don't know some days my 31.5 8208 58 loads shoots 3400-3450 then the next time I seen it at like 3250-3300. So I don't know how accurate my chrono is.
 
H322 could be the ticket. I will re-test the good loads and maybe experiment with seating depth but I was able to ring out a good group that ran 3475fps avg and a second at 3550fps. 58gr vmax cci450 and new nosler/ssa.

For me, 8208 was not stellar. Relatively slow speeds and accuracy went from slightly worse than mediocre to embarrassing. YMMV
 
Todays runs over the chrony with H322.
6x6.8 Savage bolt build, 22" BHW bbl.
2.280"col, cci 250, R-P brass, 55g varmageddon
Tested with a Magnospeed V3 chrony & suppressed.
All at 100 yards. 7 oclock breeze at 11-17 mph, 49* & sunny.
Not a single sign of pressure.
31.5g H322 fills up to just inside the neck on the R-P brass.
I could do 32g easy & after that with the 55g it would start to be a compressed load.

H322 powder:
28.5g = 3288 fps
29.g = 3362fps
29.5g = 3415 fps
30.g = 3496 fps
30.5g = 3502 fps
The above went into a .405" group

31.g = 3576 fps....2 round average
31.5g = 3609 fps...3 round average
The above 5 shots went into a .506" group

87g vmax
29g Varget, 2.280" col
cci 250, R-P brass
2861 fps average of 5 rounds, .588" @ 100 yards.

Did you ever come across your data?
