Fioochi has two sizes of primers. The 615 & 616. One fits Us hulls and cheddite hulls the other fits the Rios and foreign hulls. I forget which is which

That's B.S. B12!
They are both the identical same size.
The difference is, one is hotter than the other. 616 - Hot. --- 615 - Mild
The size is the SAME!

With last year's Winchester primer rebate were they not similar priced?

Winchester Primers net price after rebate was $88.00. You could buy 3 cases, 15,000 primers. Receive back up to $100.00
