Maybe this will help…feeds well Sigs (various), Springfield XD, no flattened primers… Very similar to max Silhouette listed as noted : Tested the new : Nuke 124gr. JHP with 5.4gr. of Ramshot Silhouette, Winchester sp primers, Winchester cases, cartridge oal: 1.065 Chrono data yielded average velocity of 1118 with Extreme spread of 17 and standard deviation of 7 from a Sig 320 5″ barrel. Good accuracy with no unburnt powder. This load is listed as a non +p but max saami working 9mm load, with the Hornady XTP 124gr. bullet. Velocity is similar though just slightly lower substituting the Hornady 124gr. XTP bullet. Accuracy of the RMR Nuke JHP 124gr. is very good with this load.
