338 Lapua Mag w/ 250 SMK\'s any good powder choices

Hello guys just starting to post here, long time reader.
I have decided to load some 250 smk's for my 338 lapua, I have Retumbo on hand as many have said this works well with 300 smk's. Has anyone had any luck with retumbo and 250's? If not can anyone suggest a good powder for 338 lapua w/ 250 grn bullets. I shoot everything Naked BTW, no moly.
thanks for any help,
Chris

H1000 works really well for 300SMK or 250SMK. I have found it to be slightly better than Retumbo for accuracy.

Thats is what many members are emailing me. Try H1000, I already have Retumbo, was gonna try it with 220smk's in 300wm, so Ill give it a shot with 338 and get some h1000
thanks,
Chris

If you can get obtain some WC872, you won't be dissappointed! I use it quite a bit in my .338 Lap. Due to prior problems though, I can't send you any recommendations on loads.

I like REL 25 the best of all that I have tried (H1000, Retumbo)

SR90,
I seem to remember that you also have a timberwolf (PGW). What load do you use with Reloader25 for 300SMKs (moly-ed). What are your velocities? How do you like the H1000?
I'm getting 2780fps with 92.0 of H1000.
