264 WM & 143 gr ELD-X accurate load

Really interesting stuff about the 143s which are working good for me in 2 rifles - a 260 Rem and a 6.5mm WSM. I attached a pic of one of my recent targets from the 260 Rem which averages about 0.36 MOA. The 6.5mm WSM groups in the 0.5 MOA range but is better than that on dirty cold bore shots where it seems to hold around 0.25 MOA. Being hunting rifles I really only care about the cold bore shot. So from what I've seen my buddy should be able to get this bullet to work.... but maybe they just don't like the 264 WM. Thanks for the info.

I'm running the 143s in my 264.
Nosler brass
73.5 gr R33
215m primers
2.235 oal measured off the ogive I think im about .005 off the lands
It will shoot 1/4-1/2 moa as long as I do my part on the band switch. I think it would be more consistent if I had a muzzle brake
I neck size only as well. Hope this helps

That is the kind of info I was looking for - a recipe that is known to work. Thanks. I'll pass this on to my buddy.

What velocity does that load give you out of what length barrel? Thanks again.

It's running 3125 in a 26" barrel
I did a ladder test, and when I got to this charge I stopped looking, reloaded it and went back to the range got the same results.
There may be another accuracy node at a higher velocity but I didn't search for it.
2 groups @ 1/4 moa were good enough for me
