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, extruded propellant, developed
in the 1970s to replace IMR4831 which had been used in the M48A1 round.
It has about the same propellant energy as IMR4831 when compared in equal
volume, not by weight. IMR4831 data can be used, but charge weights must
be reduced by about 15%.
There were three (3)different lot numbers of IMR7383 released as surplus by
the military. There is quite a difference in burn rate between these three
lot numbers. When sharing data or info on IMR7383, be SURE to reference lot number.
This is new powder, not pulldown.
$70/7# jug IN STOCK = $10 a #???

Just for reference this M48A2 round was used in a 50 cal M2 BMG mounted on a 105 howitzer like we use a scope. I saw one when I was working at LC in 1969.

I don't shoot nothing bigger than 300wm but maybe the info will help someone shooting 50 cals and such, not enough room to stretch one out where I live, there is a town every 3 miles in KY basically, with a pop of 100
