[QUOTE="backwoods83, post: 795685, member: 29890"] Not optimistic at all, I can run 100% plus charge density in a weatherby case with H1000, RE25, RE33, Retumbo, Ramshot Magnum, and a couple others. What can you do that with in a rum case, US869, Imr5010, H50bmg and a couple other very sensative powders. And yes I can get 3000fps from a 24" barrel, its got a lot to do with how you load, not what your loading. In the words of Chuck Hawks, the 300Rum and 30x378wby are close to useless, I have yet to understand why one feels the need to neck two cartridges originally designed as elephant rounds down to 30 caliber. Yes you may have gained 120fps over the wby, but at what cost, 98grns of powder instead of 86, and the 300wby brass can live decently at 68-70k psi, rem, fed, or nosler rum brass will not, so in a nutshell the wby will duplicate the rum at 3k psi higher, have better brass life, a 1500+ round barrel life, and use 9-11grns less powder.
