[QUOTE="Jud96, post: 1184222, member: 69478"] Start with Retumbo around 85gr and work up until you see pressure signs. Max load in the books is around 89-90grs of Retumbo. A lot of guys shoot Federal 215 primers. I have some, but have not yet tried them. My best group so far with my .300 Win Mag was with Remington 9 1/2 Magnums. They seem to work great and have given me excellent results. I have the same rifle but in .300 Winchester and it really likes Hornady 208gr A-MAXs and IMR 7828. The 7828 might be a little fast for the .300 RUM, but it is normally readily available and has worked great for me. [/QUOTE]
