Just traded for a 5r Remmy 300 win mag. Does anyone know of any magic loads for the 300 win and 178-180 grain pills. I shoot the 178 amaxes in my 308 and would like to just use these if possible. I understand I will have to work my own load, but there are several loads that work well in most guns like FGMM in the 308's. I would like to stick with a temp stable powder like H-1000 or H4350.
