Re: Reloading 30-378???
Retumbo, H1000, Magnum, H50bmg, in that order depending on what's easiest to find. Definently Fed215s. You may wanna try the 200 or 215 hybrid if you can find them or the 210 accubond lr, they aren't as seating depth sensitive. All of the powders listed are extreme powders so they aren't sensative, magnum is a ball powder but very stable.
