IMR 1744 ?
A friend was given 10lbs of this and has no clue what it was used to load. A call to IMR said they don't even have records of it anymore and that it was used by the military back in the 30's-40's. He says it doesn't show any signs of deterioration.
Anyone have any info on it?

I've got a powder burn rate list with 246 powders on it and that one is not listed. If there was a WC number, like the later military ones mabe we could help. 0 -
makes good fertilizer, sprinkle in garden or on lawn, water in. 0 -
Got data for 17 1/2 but not the listing you gave. I know there were quite a number of small production lots of smokeless propellant early on in the game. Most had one or more shortcomings and they were never produced again. 0 -
Start looking in some OLD reloading manuals at gun shows.
I once got a can of Win 785, long out of production, but at least Winchester still had some data on it in a late 70s manual that they were able to photocopy for me. So I know it can be frustrating.
I'd guess it to be a rifle powder but beyond that couldn't say. So even working up a load with a chronograph and watching for pressure signs would be a hard sell without some start point.
Don't toss it. I'll see what I can find out.0 -
xxCross, they did say that the 17 and 1744 powders were almost exactly the same, more to do with the lot# than actual difference in the powder.
Jonk, appreciate it, I've read through old books I haven't looked at in years and can't find a single reference.0 -
Well if it is similar to IMR 17 I know that cartridges of the world has some info on the original loading of THAT as it appeared in the original M-1 ball round. I'll look at that and it should give you a start point anyhow. 0 -
I have several books that list 17 1/2. As I recall, the problem with that propellant was that it contained tin. The tin would build up in the bore and was really hard to remove. Thus discontinued! 0
