I've been reloading my .338 Lapua regularly with Lapua brass and 300gr Scenar bullets. It shoots awesome with Retumbo powder. Wanted to try something different so I recently purchased a box of 250gr Scenar bullets and can't seem to find any reloading data. No idea where to start with powder amounts or if I should even try another powder. Any help would be greatly appreciated. Hopefully someone out there is using this combo and can help.
