My statement was too general. Tom has listed more primers than I knew about or generally see for sale. Looking at my IMR handbook, only the Fed 209A primer gives a much higher pressure than the Win 209 or Rem 209P. From the Claybuster wad guide the Cheddite is about the same as Win. I believe the Fiocchi is the same as Win. I couldn't find any load data for some of the primers Tom listed. So yes, there can be more variation and one should check first. Paul
