Some 6 WOA data from the range today

Got some new powders to try with my 6 WOA. Shilen 22" barrel. All 7 1/2 rem primers and 58 vax. Used H322, H335, and H4198. This has been a little finicky to load for. Still haven't found that magic combo yet, but I may be a bit too picky. 1" groups have been easy, but have not got any of the clover leafs I can get with my 20 practical. 10MPH tail wind.

58vmax COAL 2.256---.010 off lans
H322
28.2 3236, 3204, 3222 Aprox 1.25"
29.3 3383, 3363, 3355 1"
30.0 3422, 3474, 3432 1"

H4198
26.5 3327, 3352, 3379 1.5

H335
30.0 3214, 3158 1"
30.5 3282, 3298 1"
31.0 3434, 3450 3/4"
31.5 3517, 3565 3/4"
32.0 3638, 3675 1/2"

Obviously I was quite impressed with the speed I can get from the H335 and the improving accuracy with increasing charge was nice too. I could easily put another grain in the case at 32 grains as I was showing no pressure signs. However I don't know that I need any more than that. Unfortunately the last powder I tried was the H335 and by then was just loading 2 per weight and ran out of daylight. looking forward to getting back out again. Its going to be hard to take the 20 prac (40 Nosler BT)when I am getting the same velocity basically out of the 6WOA. Appreciate any feedback
 
I can look at my data but if memory serves me right try H-380 and 65 grain vmaxes. I think my best groups were with 75's and they pushing max or above with SSA small primer brass. PM me if I can help!

Mine shoots 70 Sierra HPBT with 28gr Varget pretty good. I first tried the 107/105's to no avail. Then started moving down. You know the drill, 90's, 80's, 70's and finally 60's. The 70's were way ahead of the bigger bullets. The 60's shot pretty good. With a Krieger 7.5 twist it should have shot lights out with the big bullets. Oh well.

In my 6 WOA(Made by John Hollinger at White Oak Armament), I use Benchmark under 65 gr. VMax bullets, for predators/varmints. The velocity was higher than I expected(I have to check my data), and it is exceptionally accurate. I was flipping p-dogs with these loads, out beyond 500 yards, with some consistency. A friend has a DTech 243 WSSM, and even he was impressed with my first shot hits. I haven't had good luck with most spherical powders, and after an over-pressure experience with H-380(in a 22-250), that was off my list, for all cartridges. Good data is hard to find for the 6mm WOA, or similar wildcat cartridges. I used some data from John, and worked up slowly, to find this load. Very happy with the temperature stability, the velocity, and accuracy with Hodgdon Benchmark.

Thanks for the input from all. I didn't believe the velocity on those rounds either and took a double look at the read out. I'm pretty sure it's reading correctly because I shot a couple factory loads of 60 vmax out of my 16" 223 also and they were around 2750 which is what I expected.
Hoping to get back out soon to do some more testing with the h335.
 
What brass are you using?

I tried the 6 WOA in an AR just long enough to see that it was very capable. I then built a CZ 527 in that caliber, and it's one of those guns that doesn't exist. With an 80 hr Sierra Varminter it will shoot better than 3/8" not just all day but all year. I wouldn't sell it for a million.

My predator load is a 65 vmax and benchmark. It will shoot 3/8 most of the time, and has ever shot over 3/4.

I've got about a dozen other loads that range from really good to excellent. It's just a pleasure to own. This summer I'll be having it custom fit into a manners stock, and setting the barrel back to get a fresh throat.

Ballistically, it's a 6x6.8 SPC with the shoulder bumped back just a bit and improved 30 degrees.

In reality, it is one of if not the best predator cartridges you could outfit yourself with. It's also one of my two favorite deer rounds.

That depends on where hit & how close/far out it may be.
The 6woa/6dti are brothers to my 6x6.8 and I have yet to have a exit hole that was bigger than a 50c piece. I run a 55g nosler in front of 32g h335 as stated above and am only 64fps slower than the 6woa with 32g h335 & 58g bullet.

Anyone who says it will doesn't own one.
It will exit (again depending on where hit) from the 100s Ive shot w/the 65g vmax in both my 6x45 & 6x6.8.
It may not leave a big hole (depending on entry spot) but Ive still had exit holes from shrapnel size holes & up w/said 65g vmax.
Again ALL bullets will make an exit hole depending on where its shot.
 
It sounds like a neat round. I'm amazed at the number of new or different rifles since I have been on these sites. It is truly astounding and informative. Thanks Rudy

I suppose if you hit one low in the leg or through the tail, it could perhaps exit. I can't imagine why anyone would want to do that though.
 
^^^There are hundreds of coyote with missing legs that have been shot at & missed out there.
I see at least 2-3 like that a year that come in off public lands to the ranches I call on.
Most any bullet that hits low & back (belly) or a bit to high on the back is going to exit in a mess, pretty much what Im saying overall.
Now back to the 6woa shooting/loads we are drifting.
 
CZ, Im using SSA brass. Im going to get back out tomorrow morning to check those velocities again and see if I can get it really dialed in.
 
Thinking about doing one of these in my AR what do you guys suggest for barrel? and bolt? How do you form your brass? run 6.8 brass through 6-6.8 die? or fireform? This is an exciting option and also wondering on the cost for barrel and bolt combo. Does this also use a rifle length gas system?
 
Dan [beeep] out of Arizona made mine. The 6 WOA has it own die set and its a one step process to neck down. The brass does change a bit after the first firing, but I have not noticed much change in POI between once fired and new brass.
