I got a big load of this stuff and its just not for me. I bought it for a particular weapon and the barrel is too short so the powder isnt burning completely. I can line you up with load data links on the net for IMR7383. Powder info; IMR7383 This is a slow burning stick powder originally used for the Cal. .50 M48A2 Spotter/Tracer round. This is not the same case as that known as the .50 Browning Machine Gun cartridge. This powder is NOT recommended for the .50 BMG round. It is a very bulky, single-based powder, composed of 85% nitrocellulose and 15% stabilizers, flash inhibitors and graphite; that was developed to replace the IMR4831 powder that was being used. It has about the same propellant energy as IMR4831 when compared in equal volume. IMR4831 data can be used. Begin with starting loads, reduced 15% by weight. This is new powder, not pulldown. My unopened 7 pounder of IMR7383 for your 4 unopened 1 pounders of (any combination) 4895, 4198, 3031, or Varget. 2 available.
