Favorite Powder(s) for .45 ACP
It depends on application. For accuracy: Bullseye, followed by Unique and Win 231. For all-around shooting, plinking, action shooting: Win 231 and Power Pistol. Of course, HP38 can be used anywhere you use Win 231. I have been meaning to try Universal Clays, Blue Dot, AA #5, Titegroup, WST and 700X. Some of these powders are very versatile and can be used with good results in a number of different cartridges. With 230 grain FMJ projectiles, Win 231 sees a lot of use. My most accurate loadings for 230 ball uses Sierra FMJ bullet over a carefully metered load of Bullseye. The powder burns kinda of messy, but the accuracy will make you wonder why you ever bought factory assembled ammo for you 1911.
