Has anyone made 7 WSSM for competition?

[A mf B]

I have bought 500 pieces of hornady .243 wssm brass and necked 400 to 7mm

180 eld-x

So i've been thinking about building a rifle for F Open, and some informal training to 1,000 yards.
Have been going over cartridges, and wondered if anyone has tried necking a 25 WSSM to 7mm?
I would prefer to neck down, but from my understanding 25 caliber is largest WSSM caliber.

Thoughts?

It's a interesting idea.
My spotter has a 6.5 WSSM and has done pretty well with it.
But.
For me anyways.
If it doesn't come in a blue box.
I'm not interested.......

What kind of velocity did you get with that combo?

Case capacity is pretty identical to 7-08. Imagine it would sit somewhere between 7-08 and the 7-08AI

Might be a good thing for moving a 180 in a short action.

Could not remember, so looked at my Data. It was with 183 Sierra 183 Varget at 2630 fps. 30 in. barrel. Also used H4895 at the same Speed.
