Was Wondering if this is a suitable powder for a optima , I have been reeading up on it After i went to the Range I could get on paper after three shots. I bought the gun off here and it was included with it. i was shooting the TC shockwaves 250gr anythoughts on what might need to change, different loose powder , different bullet. I friend of mine shoots the PB platinums , with 150 of 777 pellets and swears by it
