Imr-7383/imr-4064

[waco]

I have used IMR 7383.
I have an 8 lb. container of it right now.
It reminds me of petting a rattlesnake.
It can be done, but you better be real careful.
I certainly wouldn't recommend 7383 to an inexperienced reloader.

This is why I am looking for more info. Don't want to jump in blind....

I have a full 8 lb jug of the stuff, that I bought from GIBrass about 8 years ago. I've never burned a kernal of it yet, but I've read through every thread I can find, and read most of them a dozen times.
With that disclaimer out of the way, I can tell you the following.


Lot numbers:
post #5 in this thread, summarizes the info I've read about lot numbers.

All, I've been using IMR 7383 for years, primarily in my .243Win. (now sold off) and .30-06 with jacketed bullets, with nary a problem. My unnumbered lot is ~the same burn rate as IMR 4831 and is much "fluffier" than IMR 4350. Lately, I've been using it with 160gr. cast bullets in my SKS with LR magnum primers and have been very happy with it with respect to accuracy and not tossing the ejected brass a country mile. If you already have a jug, use it, but start conservatively and chronograph your loads: It is a good propellant especially since it was once dirt cheap. Now? maybe not so much (because of its price).

I picked up 45 pounds of it for $5 a pound.

The stuff I have has hollow sticks like SR4759 only much thinner.
