I see you say sarcasm font but is there really anything I should know about the Cheddite primers cause I just bought a few packs.

Some find that the Cheddite might increase your pressure by 100-300 PSI. I have had Cheddites for years and have neve seen any pressure issues. I don't load snotty shells nearing max pressures. No reason to shoot shells like that, IMO. Those are not kind to the old stocks on our vintage guns. If you're not sure about what a certain load is doing, make up a half-dozen shells and send them and your recipe to either Tom Armbrust or Ballistic Products and have them pressure tested. You might have to drop your usual powder charge by 1 or 2 grains, then again your load might need no change if you are well below max anyway.

I've shot a LOT of Cheddite primers (especially in the last couple of years), always with results that were just fine. I tested some identical loads, Cheddite vs. other primers, and found several times the Cheddite actually came in 200 to as much as 500 PSI less. I'm with Mike, no "snotty' loadings. My conclusion is good patterns kill birds and clays, not velocity. Don't think beating yourself and fine guns up adds to the bag.
