[QUOTE="adamsredlines, post: 3703367, member: 40561"] This may be common knowledge but I just learned it last night and find it pretty dang interesting. Could you imagine this as a commercially available cartridge cartridge? I wonder what the ballistics would be like? This was using a .30 cal 30gr projectile. I couldn't find anything about the projectiles shape or material. "The .30-378 was originally designed by [URL='https://en.m.wikipedia.org/wiki/Roy_Weatherby']Roy Weatherby[/URL] as an anti-personnel/anti-materiel military cartridge for a government contract.[URL='https://en.m.wikipedia.org/wiki/.30-378_Weatherby_Magnum#cite_note-gdo001-4'][4][/URL] The cartridge was created by necking down the [URL='https://en.m.wikipedia.org/wiki/.378_Weatherby_Magnum'].378 Weatherby Magnum[/URL] to accept a .308 in (7.8 mm) diameter bullet.
