I'm looking for a different powder that I can use in my .357 mag, 45 acp and 45 colt. Currently I'm using Unique in all three calibers but I'm looking for something that will meter better from my Uniflow. This powder will be used for just my plinking loads and I'm thinking that W231 would work for all three but I'm not familiar with it. For my heavy loads in the 357 and the 45 colt I use H110/W296.
