Im posting this for you 6x 6.8 loaders ( if there are any here) since as we all know there is no data for this caliber besides what the shooters post & that's very little.
My build, 22" BHW P3 1/10" twisted, AR15
Shoots like a shotgun with many powders and nice & small groups with others. I have not had any barrel shoot all over like this one no matter the loads or powder.
All shot w/bipod, rear on a bag & tucked into my shoulder inside the shooting house over a chrony.
Remington 6.8 brass necked to 6mm. Large primer pockets.
All loads were at 2.280"
All primers including magnums were perfect, no craters, no over pressures. NO FTF, NO FTE all ran in my AR perfectly.
IMO x8208 is overrated as it failed to group good w/the weights I am shooting.
This will not be a heavy bullet gun, 65g MAX for coyote.
My old 1/10" P3, 6x45 outshot this 1/10" P3 by miles with the same powders, never did it go over .900"
This is just MY observation. It does shoot well with some loads as you will read below.
They may shoot better or worse in you gun, I make no promises whatsoever here, use at your own risk/discretion!
