I understood that at one time European primer pockets were different in size than those intended for use in the U.S. and that Cheddite manufactured primers in both sizes. I also heard that Fiocchi did/does the same.
A friend I shoot with shoots quite a bit of 16 ga. Last year he experienced an inordinate amount of obviously light loads. He was perplexed about the problem as he has been shooting the particular load for years. Except, that is, he attempted to economize a bit and started using Cheddite primers. He went back to Win. primers and the problem went away. So, maybe it depends on the powder/load being used. I believe he loads Greendot.
