I am trying to put together some 45 Colt loads to be used for informal shooting in Uberti revolvers. My target would be a 255g bullet moving at 725-750 fps.
I am using 255g LRN Hornady bullets. I made up some loads with 6.1 g of Winchester 231, and according to Hornady's book, this should actually be in the 750-775 fps range, but I only get about 625 fps out of a 5.5" Ruger Blackhawk.
Is this difference from the book to be expected? I would think the book ought to be closer than that... its 150 fps different.
Are there better choices out there than Win 231 for light 45 Colt loads?
Also, how are Hornady lead bullets compared to Oregon trail lead bullets?
