[QUOTE="Lefty7mmstw, post: 922440, member: 48043"] 4320 is one of the original powders for the 30-06 and well suited to it with mid-weight bullets. It'll also make a [EMAIL="375h@h"]375h@h[/EMAIL] sing a heck of a song:D:D:D, and that's why I have a keg of it. 243 win with 80 gr. pill IMR Powder IMR 4320 Bullet Diameter .243" C.O.L. 2.635" Starting Load Grains 37.0 Velocity (ft/s) 3,132 Pressure 44,000 CUP Maximum Load Grains 40.5 Velocity (ft/s) 3,339 Pressure 50,600 CUP 30-06 with 150 grain pill IMR Powder IMR 4320 Bullet Diameter .308" C.O.L. 3.250" Starting Load Grains 49.0 Velocity (ft/s) 2,850 Pressure 51,600 PSI Maximum Load Grains 52.3 Velocity (ft/s) 3,016 Pressure 58,000 PSI look around a bit for data; this powder at one time was very popular but with big is better like rifle cartridges are today, some of the good mid speed powders just don't get the respect they deserve.
