Has anybody here ever used Hawk bullets,I have a new 38-55 cowboy and finding jacketed bullets to fit the bore which is actually .378.The .375 bullets just don't grab enough rifling to be very accurate,Hawk bullets told me that they have a.377in diameter bullet in 5 weightsand because they have an annealed dead soft jacket they will expand up to .003 when fired in my Marlin and the accuracy should be great.I need any info that anybody can give me as I intend to hunt with it this deer season.
