I can only state my experience, everyone has to decide for them selves, but if you are experiencing the differences you mention my guess is you are on the Ragged edge & any number of factors may give you a squib.


Agreed. I have switched to Clays for low pressure PRACTICE. My hunting loads (sadly used rarely...) are loaded with PB. I have personally shot PB loads down to temps in the 0*F range without problem. Any colder and I am going home anyway.
