I believe I load 'handgun only'; I like choices
'Slower' powder choices work best in my autoloaders, except at extremely low velocities.
Even then, I most often use something 'slower' than Bullseye (which is used mostly for target 38 Special).
I currently still load for 9x19, 9x21, 38 Special, 357 Magnum, 40 S&W, 400 CorBon, 10mm, 41 AE, 44 Magnum, and 45 ACP.
(In the past I have also loaded for 38 Super, 357 Maximum, 41 Magnum, 44 Special, 45 Colt, and 475 Wildey. And maybe some others...).
I shoot mostly 9x19.
I currently still use AA2, AA2 Imp, AA5, AA9, Bullseye, Nitro 100, 700X, W231, WSL, Unique, Universal Clays, Power Pistol, HS6, WAP (man I gotta lotta WAP --my first choice for 9x19), 3N37, 800X, Longshot, N350, HS7, Blue Dot, AA9, 2400, N110, H110, and W296.
Mostly.
