Another Unique load comes from BPI. Fed hull cut to 2 7/8", Fed 209A primer, 30 gr Unique, x10x, VP100 wad, 1/4" filler, 1 1/4 ounce lead shot, rolled crimp. Velocity 1130, pressure 7070. Fed209A increases pressure over Win and CCI but roll crimp reduces pressure.
Unique is a little faster than SR7625 which has given good service in the short ten.
