Long time hand loader & lurker to the site.. (just registered)
Have learned the 45 acp round is NOT @ all fussy about which powder is used in loads.
I've personally used at least a dozen different powders & had good results with all of them.
Some are cleaner burning than others..some fill the case more, etc.. but all will propel the bullet
of you choice down range in an accurate manner..the shooter makes most of the accuracy difference.
Most recently, I'm using HP-38 (same as 231).. Titegroup, & Clays (cleanest burning power I've used),
For years I used to use a lot of A/A#2, A/A#5, Bullseye, Red Dot, but recently tried, & started using
Shooter's World Clean Shot, & Auto pistol.. both work very well.
Used primarily cast bullets, from a variety of sources. Had a friend that used to cast for me.
When I watched him work, decided casting is not for me (exposure to lead fumes, potential for burning myself-not worth the trouble)
Tried plated bullets for a short time, then found Hytek polymer coated bullets, from Falcon Bullets,
& Bayou Bullets. I like Falcon > Bayou, because Falcon uses some molds that cast TC shaped bullets,
& Bayou has more RN molds, it seems. I still buy from both companies.
I load 230gr, 200gr, 185 gr pills, like the accuracy (& neat holes) of the 185gr & 200gr best.
I'd suggest you try a variety of components & determine what you like best..there are no bad combinations I've used,
in my experience. I did stop using Bullseye, after many years as I didn't like the residue on my pistols & hands.
But if my powder supply runs low, I know it will work.
Happy loading !
