Nope, never came with any kind of spacer. I simply bought another die set and I've been rolling ever since, and have made more .357 Magnum since getting that set than .38 Special -- though I've made a lot of both.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
