They don't list it....anyone got a reason?

They don't make it. S&B specializes in European stuff pretty much. Try Prvi Partizan. Graf's is a good place to start.

Strike Graf's.. Try Powder Valley.

I like the s&b SPCE.
Thought I'd pick up some and make brass.
They do a good bit of .30 cal parent cartridges.

The PRVI 7mm-08 is pretty good stuff.

I bought some PRVI 243 win awhile back to load for my nephew, and it was not good at all. Difficult to get primers in several cases. This was awhile back, YMMV
