For the data base :

.32 H&Rmagnum
Starline brass
Any SPP
3.1gr W231
Berry's plated 83gr HBWC
[NOT seated flush with the case mouth, but 1.20" COL]
Light crimp from Lee factory crimp die

I have been loading since the late 60's, not any expert, but I began for the sole reason of making accurate loads for a given gun......because they all shoot differently...RIGHT ?
This load [posted above] has been an incredible performer, the absolute best accuracy, of all the .32 rounds I have concocted........in 2", 3", 4", and 5.5" barrels. S&W 632, SP-101, Taurus 327, Blackhawk .327, GP-100.........I have never seen one round do this before. It shoots almost identical from each gun. I would have surely bet you it was not possible.
