I live in Arizona and have been been shooting a Ruger Super Blackhawk 44 mag 7.5 inch barrel for years. I also reload for this revolver. Well if you carry this anchor hiking for a day it gets a tad heavy by the end of the day. Great for snakeshot and rattlers but to heavy. I recently bought a S&W model 4006 semi auto. Before I even fired the piece I had my dies ordered and 1000 pieces of once fired brass. I have ordered 180gr FMJ bullets for this project but they are on backorder. Since the bullets are backordered i have had lots of time for more research and case prep. I did manage to put 500 rounds of factory ammo through the pistol to start the break in process. It only reminded me why I reload for the 44. I dislike factory ammo with a passion. For me its hitting the bull not saving on the cost that makes me sit at the bench. That was my personal intro guys now to the meat of the thread. I have 1500 40S&W once fired federal cases decapped, annealed, tumbled, sized and reprimed with federal small pistol match primers. I need powder suggestions. Frankly I am slightly confused by the 8643 recipes i have seen for this round including 1 for 2400 magnum powder which I use for my 44 rounds. Ahhhhh NO!!! Can I have some feedback on this "Medium burn fluffy fill the case" stuff I read about? Again the recipes I see range from 3.5 grains to 11 depending on the powder. 3.5 grains does not sound very fluffy to me it sounds hot. I find myself looking at power pistol and blue dot as my main choices. Whats is going to give me the best group? That bullseye don't shoot back but it sure kills me. Help me git it!!!!!!
