Have been lighting up 44 Mag, 180 grain Sierra bullets, WW296 with CCI 350 primers. I now only have CCI 300 primers and would like to know what the CB Reloading Pros would do since 296 likes the 350 primers? By the way, I am shooting a Desert Eagle and because of the gas system, do like to get the best burn of the ball powder. Thank you for your time.
