338 WM Retumbo

[Gernest2]

Anyone out there using Retumbo or H1000 for their 338 WM? I'm using 200gr Nosler Accubonds, but the Nosler manual doesn't list those powders for it, not sure where to start. Thanks

No, you won't see those powders being used, they're miles too slow for the expansion ratio of the 338. RE19, H4831sc and RE22 are the slowest powders you want to use. RE19 will give the best performance of ALL powders in the 338, even H4831 is on the too slow side as is RE22. H4350 gives good performance with bullet weights up to 225gr, but pressure is high, in my experience.
I run 225gr Accubonds with 76gr of RE19 in Rem brass and WLRM primers @ 2890fps in my 26" barrel.

Cheers.
