To me, slightly more "snappy" than unique (more of a push) @ same velocity out of short barrel .45 colt using 255gr .452 lead.
Accuracy was slightly better than unique loads within the 25yrds I tested.
I use it in reloading 38 Special, 357 Mag, 44 Mag & 500 Mag. I get excellent groups in all of these calipers. Just remember "A little goes a long way". Carefully measure your charges and follow reloading data.
I use it in 38spl,32 S&W Long,and 45acp. Burns clean and meters well in my Uniflow.
Only think to watch out for, it's such a low volume powder(takes up very little space) you could double or triple charge large volume cases(38,357,45 Colt,etc).
I use it for everything I load, mostly because it's what I can get locally. 9mm, 38 & 357, 45 ACP and 45 Colt (standard and R/O loads). Been happy with with it in all of those. It takes up very little volume in the cases so be careful as it is easy to "double charge" the load without it being very noticeable!
