I have never seen .356 bullets for a .356 Cartridge. I seriously doubt if they exist. I have seen .357 pistol bullets, and even .355/9mm, but havent seen any such beast as a .356 bullet for re-loading. As a matter of fact...I have never heard of a .356 Die set. I have heard of a .358/.356 Winchester die set. They are one and the same. I shoot a 356 Winchester and I use .358 dies for it. If there is a die set that works better for this cartridge...I want to know. The only difference that I know about is the shell holder.
