I really like Doubletap ammunition (http://www.doubletapammo.com/). They are the leaders in specialty pistol and rifle ammunition and are best known for loading calibers like 10mm (15 different loads!), .41 magnum, 9x25 Dillon in addition to more mundane stuff.
Their quality is very high and on par with the best producers like Black Hills and the now defunct Pro-Load.
They are now loading .38 Super with my favorite Barnes XPB (115gr) loaded to 1425 fps for 519 ft. pounds of energy... I have a few boxes enroute. Expect a range report soon.
