Re: 300 rum ??
The 2 210 loads have more room, but that is where in my gun in my location was the best efficiant. The H-1000 will at some point start to drop in velocity the more you stuff in it. Retumbo on the other hand will start opening up primer pockets and you would only get 2 maybe 3 shots out of the brass before you toss them. Both shot excellant as you see from my notes, but I'm staying with the 185VLD. It has prooven itself on a steel gong at 500yds plus a few kills on some hogs and I am very happy with the results I have found.
