I just entered the 32 field this fall. With a 327FM in a Ruger Single 7 stainless 5.5" slugged 0.313 size to 0.314 PC. I found a NOE 315115 gc. drops 0.315 @116 gr. Just to play I loaded 25 rounds, 5 each
Powder - load wt
H110 - 12.0 gr
Book says these should be around 1100 fps
700X - 4.2 gr
HP 38 - 4.8 gr
SR4756 - 5.2 gr
Universal - 4.6 gr
Now that I got shooting it out of the way. I'll go back and run H110 and 700X loads past the LabRadar and begin working up mild and mag loads.
