i have tried both 41's and 7 1/2's. I am going to reshoot some stuff with the 7 1/2's but I think it may be an overall better primer. I showered lower speeds and more pressure with 41's on my last chrono session. I will just have to wait to shoot again before making a final decision. I will post the results.
How is the 30 WSSM working out?
Thanks in advance
