Went out tonight and shot 65 and 58 gr Vmaxs I am going to dump my brass as it must be worn out so I used once fired Hornady brass 8208
shot at 100yds it was dark. But I'm happy with the results so far. Dropped one out in both groups but I think it was the jerk behind the trigger.......

What cartridge? I also went shooting a few loads tonight with my 6x6.8 using the 58 VMAX.I normally used 8208 but I am pretty sure I am going to switch to H322.
 
I'm thinking the same thing. Coming down your way to deer hunt the rifle season. Would like to use the 6x6.8 but will have the 7 mm mag also.

Are Y'all using 450 primers? I have very similar results with groups as you fellas, but my experience on coyotes with both bullets is that the 65's flatten them with no exits. YMMV.
 
Yes CCI 450. 65s shoot good too! They shoot so close I could interchange them but need to shoot both of them out to 500 yds

I use CCI 450's also, I did clock the IMR 8208 and 58 Vmax, but will have to look it up. The H322 loads I haven't clocked them. The other day is the first time shooting that powder in the 6x6.8

This load shoots the best in my 6x6.8 from ritch . It shoots 75 grain v max even better over 30 grains of ARcomp

In an 18" BHW tube 31.5 H322 was 3460
The same day 31.5 8208 was 3362

31.5 8208 in a 20" gave me 3425

In a 24" tube 31.5 of 8208 was 3471. Bumped to 32 grains it ran 3511.

I only shot the H322 for some verification on a load in the 18" gun. Not all the barrels shoot it well and my go to is still 8208.

Varminter .223 has my RPG 6x6.8 upper. He loaded and chronoed a few rounds:

31.5 Grains of H322, 58 vmax, cci 450 - 3671 fps 5 Shot Group .958" at 100 yards

30.0 Grains of AR Comp, 75 vmax, cci 450 - 3322 fps 5 Shot Group .934" at 100 yards

My 31.5 grains of 8208 with a 58 vmax were around 3465 for reference

this should be a yote smashing machine
