I load down for several different handgun rounds but only have used Bullseye powder to do it. I loaded abunch of .38 SP loads with 2 gns. of Bullseye for some friends that compotation shoot for 15 to 25 yrd. targets they group great. At 50 yrds. they aren`t worth a crap, but I loaded they a bunch of 3.2 gn. loads, the most accurate Bullseye load I tried. There is almost no powder in the case with these loads and they shot very well. I tried pointing the gun at the ground and then in the air and could get no fliers or odd sounding rounds. I guess that there are afew more powders that are also good for loading down handgun ammo but Bullseye is the only one I`ve used because I`ve had such good luck with it.
I have never down loaded for the .500 S&W yet. I`m still haveing to much fun shooting the full house loads. I did fire 45 rounds over sand bags 1 day and that did have my hand shakeing alittle, but off hand I think I could fire several hundred rounds in a day. ( If someone else was paying for the ammo.) If I can find some cheap cast bullet I will start down loading the .500, but as long as all I can find is high dollar bullets I`ll keep on loading them hot.
I sure would like to have some data for those 700 gn. bullets. :roll:
