    Hi everyone. I checked Lapua and Hodgdon data, but neither list data for the specific combo of Retumbo and 300gr. Scenars in the 338LM. I cannot find the 300 SMKs ANYWHERE, and that is what I would prefer (and what Hodgdon lists in their data). I know a lot of people have used this combo though. Where is a good starting point? Thanks

    I'd start at 88 gr of Retumbo. 89.2 gets me 2700 FPS out of my 26" barrel. I have loaded up to 90.5 gr. at 2750 FPS without any pressure signs.
