Home Forums Hunting & Shooting Hunter's Campfire 6mm case same as 243 ?

6mm Remington is based on the 7x57 case whereas the .243 is based on the .308. A .243 mag might work, then again maybe not. Likewise, a 30-06 mag might too. Either might work and either might work with a little tweaking. Or maybe none of them will work at all.
