Difference in Cheddite primers?

[Andrew Frank]

The yellow box is just old, if you order them from Brownells they will be the pink and blue. They are all CX2000s. If you get pre-primed hills they will have a different color primer sealant but they are also CX2000s

I compared loaded RST shells in 20, 16 and 12 gauge. All had the CX2000 primer, based on the comparison photo of the three Cheddite primers.

Anymore the only primer I prefer not using is the Fiochi 616 . I loaded a bunch of 28’s for a friend years ago on his press using his components and he had the 616’s . I got them in the nice old style AA hulls but none would hold WIN primers after that.
