[QUOTE="J E Custom, post: 1489261, member: 2736"] I have the SAMMI freebore for the 378 case and this allows me to load a little hotter. Also I am using the 200 grain bullets for maximum powder capacity. I tested all the way to 122 grains but found very little increase in velocity with the 28" barrel. This was also using H5010 and the best load so far is 114 grains of 50 BMG. Caution should be used when loading this cartridge, because there are many different variations in free bore and throat dimensions. I have re chambered several that the owners had taken liberties and changed neck diameters and shortened free bore to get close to the lands. These chambers will not tolerate factory loads and normally blow the primers. J E CUSTOM [/QUOTE]
