Sorry if I posted this in the wrong area if so please move me. I have been loading for a couple of years and would like to get into shooting in the IDPA, just signed up for the introductory class at Harvard Gun Club in March so my question is what bullet weight would work better st ? 155,180,200 gr. and does FMJ or straight lead or does it matter? Like I said new at this sorry if its been posted before.
