I bought the Knight MK 85 from a friend of mine a few years ago. he gave me everything I needed at the time but I recently ran out of primers. Which ones should I go with? I bought the Winchester Triple 7 209 Primers but they don't fit in the capper I have. I honestly didn't realize how many different kinds are out there. Can I use the ones I have and just buy a different capper? Thanks for the help. I would ask my buddy but he is deployed with the military right now.
