I'm currently loading the Hornady 250 gr XTP JHP bullet in .45 Colt over the max load of 8.5 grs of Universal Clays according to Hodgdon for regular revolvers.
Speer lists their 260 gr JHP bullet in regular .45 Colt revolvers with a Do Not Reduce and only one load at 8.9 grs of Universal Clays.
So, I'm inclined to believe that in my Ruger Super Redhawk I can go a pinch higher to 8.6 or 8.7 grs of Universal Clays under the 250 gr XTP bullet?
