invest in some more manuals you can never have enough and you will be able to cross reference between the books load data. I have tried wolf, omg! Federal! Winchester and CFO primers and CCI is my 1st choice then Winchester, I have tested them and I have not seen a big difference in preasure(ALWAYS START @ THE STARTING LOAD AND WORK YOUR WAY UP!) not all bullets brands have the profile even if they are the same weight I use Hornady 115 & 124gr.xtp/hp, Mg 124gr.hp & if I need bullets asap cause my MG's haven't came in yet I use Rainier(PLATED) 124gr.hp I have not yet found a pet load so I have been tweeking I use Allients Power Pistol it versatile I use it my 40cal, 45ACP, 38spl/357mag and 44mag al measures well not that exspensive 4L b jug 53 bux powdervally.com. Purchasing in bulk will save you some money and/or allow you to shoot more.. Good luck..
