The lyman manual said it was the most accurate powder they tested in the .45 Colt with cast 250 gr Lyman 452664 bullets.
"As the name implies, this new spherical propellant was designed for accuracy. Because of the unique design, this powder provides flawless ignition with all types of primers including the lead-free versions. Unlike pistol powders of the past, powder position in large cases (45 Colt, 357 Magnum and others) has virtually no effect on velocity and performance. Cowboy Action, Bullseye and Combat Shooters should love this one! TITEGROUP has it all, low charge weight, clean burning, mild muzzle report and superb, uniform ballistics. Available in 1 lb., 4 lb. & 8 lb. containers."
I have some coming from Graffs to give it a try
I bought two Lyman 452664 molds and machined the bevel base part out of one of them to create a flat base bullet of that design.
I will be giving then a work out in a couple of weeks, weather permitting.
