First off please forgive the grouping it was getting dark and I was rushing to get bullet performance and FPS results
below is a new powder color I was and still am testing
load is a NOE 454-290 with the deep hollow point pins 49/49/2 COWW/PB/HSB alloy
powder is 9.5 grns Unique ..... lab radar reports 1211 FPS
shot from a Henry Big Boy brass frame 45 colt 16" barrel at 50 yds into plastic 55 gallon drum filled with rubber conveyer belt chips
First is the load I have settled on for speed and bullet performance . It does group well when I take my time and aim properly

This load penetrated all 18" of the barrel and was resting at the back of the drum ...
recovered bullets were nearly 100% weight retention and 1 bullet measured .680 across the widest point .. All expanded very well at 1211 FPS
now as a side note at 9 grns of Unique it was getting 1144 FPS and not nearly as good expansion per the comparison pic below

67 FPS made a world of expansion difference
just thought I would share
