I use 47 grains of IMR4895 under either a 147 or 150 grain FMJ ball with CCI large rifle primers, and LC68 brass. The published arsenal load is a mite hotter than what I use but my load works fine. The 4895 that I use is a non-canister surplus powder but the burning rate seems to be exactly the same as canister grade IMR4895. I use my hard drive also to store data but I also write my loads with that 50c pencil in the notes section of my loading manuals.
