IMR7383 This is a slow burning stick powder originally used for the Cal. .50
M48 Spotter/Tracer round. It is a very bulky powder, that has about
the same propellant energy as IMR4831 by volume, but weighs less than
the same volume of IMR4831. You can work up loads using IMR4831 data,
reduced 15% by weight. It works great in my .25-06.
This is new powder, not pulldown.
