I've used Longshot for my 10mm for some time now and have been very happy with it's performance. I recently read a post on another forum for the 44 Rem Mag, so I thought I would experiment a bit. My favorite load for the 44 Mag was 23.5 gr. IMR4227 under a 258 gr. cast bullet @ 1380fps. Well, let me tell you that the Longshot is about 100fps. slower, but accuracy was Da' Bomb!!! I was averaging 1287fps. with single digit ES/SD and sub 2" iron sight groups at 50 yds.!!! I then wanted to give the 45ACP a go at it. Well, the 200gr. cast bullets were pushing the 1010fps. realm with 3" groups at 15yds.!!! I'm very happy with the all around performance of the Longshot powder and am glad I can now have one "Do All Powder" for the three primary handguns I load for. The 10mm and 44Mag are solely hunting and fun shooting while the 45ACP is for CC/SD and fun shooting too.
**THE LOADS LISTED ARE SAFE IN MY FIRARMS - YMMV!!!**

I am primarily a handgun hunter, my alloy is 50/50 WW and soft lead w/pewter at 30-1 ratio 13/15BHN. Accuracy was above par with all three cartridges, especially with the .44 Mag and 10mm, and I do believe I have found a "GO TO" powder for the mass of what I shoot in handguns!!! Just thought I would share my $0.02 of range time.
