Rolled up 5 each of 5.0, 5.1, 5.2, 5.3gr W231 under a 230gr TMJ RN.
Shot all off of a bench rest at 15M. It was a toss up with 5.1gr & 5.2gr with the best group. 5.3gr was terrible. So I have decided to go with 5.1gr. Went home and rolled up 75.
Interestingly, the best group I shot was freehand with factory CCI Blazer in the aluminum cases before I shot the reloads. Have to try and find out what the factory load is for those. Maybe the cool barrel had something to do with it.
On a side note I fired my .44 magnum for the first time indoors last night. HOLY CRAP is that loud! I don't think the old timers shooting there .22's beside me were too impressed. I think I need to find some tamer loads. I was shooting factory rounds and haven't done up any of my own yet.
