Recently moved from my life long 356 ER to a 348 Win Carbine. Bring the .348 up bore diameter, as it is could be had in custom dies like the others. This caliber came about when Winchester discontinued chambering the 33 and 35 Winchester, it splits the bore diameter difference. Necking up a 307 to 348 would be interesting. Then the mind wanders to a 348/444, which should closely match the .348 Winchester ballistics. Think these areas may be undiscovered.
