What is a safe load for 9mm using W231, 124gr plated Xtreme, and Federal no. 200 Magnum pistol primers? I also have Unique as an option.
Im not lubing and my OCL is 1.167
Ive read a bunch of threads regarding using MSPP and most say to backoff a little and you're safe. Im just not sure if the MSPP are too hot for the W231. Dont want a squib or worse.
