So I am on my third box of 1000 primers. The first box I don't remember. The second box was Remington 5.5 Small Pistol Primers. I loaded both 38 special and 357 magnum with these. Today when I went to buy primers I found out that they had 1.5 and 5.5. I guessed the one was for magnum and the other for small pistol other then magnum My 38 special rounds always seemed a bit hot and I guess the reason was that I was using magnum primers. So I am wondering if it is ok to use magnum primers for 38 special? Any harm? The 1000 rounds I loaded did not seem have any real problem.
