Ever heard of this 6.5 round?

[CaliforniaCowboy]

Was watching a video discussing barrels, the man speaking was a long range shooter. He had mentioned that when in competitions shooting up to 1K yards he preferred shooting the 6.5 Creedmore, but beyond 1K, he preferred another round I had not heard of before. Sounded like he said "Soam" or "Some with long O" 6.5 Soam? can someone point me in the right direction?

Ok, after no luck and posting here, I think I just now found it by accident. 6.5 SAUM? Short Action Ultra Magnum. Anyone had any experience with this one?

6.5 SAUM.

Yup, I did a bunch of research on it. I helped my dad build a 6.5 SAUM rifle on a Deviant action. It's a very labor-intensive round to shoot: reloading is complicated and is almost mandatory due to the non-existent commercial ammo market. The rifles themselves are almost always custom rifles, and thus very expensive. Lastly, for all of the pain of acquisition and feeding, the payoff is the most flat shooting, hardest hitting short action round available.

I am not a super long distance shooter. For what it's worth, is seems to me like a lot of guys in that crowd have as much fun tinkering with these oddball rounds and trying to get it all to jive just right for them.

If I was going to go that route, as a cheapskate, it seems like the old 7mm STW is one of the easiest straight forward ways to go.

Its exotic. I looked at it and decided to stick with the 6.5-284 just for brass availability.

Flat shooting but likely a really short barrel life

Very niche round that shouldn't have been introduced as the next big thing.

Or 6.5-06

All those 6.5 and SAUM are dying off slowly.

Hell even the wsm and wssm are in decay.
