338 Lapua and Ramshot Magnum
I am shorlty to start reloading for my 338 Lapua soon, and intend to try the Ramshot Magnum (formerly big boy) which goes well in my 300 Win Mag.
What would you assume would be the maximum charge weights behind say a 250grn bullet, and a 300 grn SMK?
Ramshot it seems have not done much reseach in this caliber, (although they are to do so shortly -I am advised by email) but I wondered if any of you out there have already used this powder, and what your experiences have been??
