Yes I've been told that the SR-4759 powder had been scratched from production, but I have about 10 pounds of it. I figure if I've got it I may as well use it. So I have a few questions I'd like to put out to shooters who are familiar with this powder.

Having tried several different powder measures I come to the conclusion that this powder doesn't meter that well. Have any of you found a measure that you find better suited to this powder? So far the large Harrell's and the RCBS Uni-Flow have been about the best for me.

Question #2 Over the years I've found slight differences in some lots of powder. One that was apparent many years ago was 2400. I just use that as an example, and I don't want to get into that. I'm sure that there is some one who has used SR-4759 for many years and could answer this question. How is this powder from lot to lot, does it remain consistent?   

Would like to hear your thoughts and suggestions.

                        Thank you, Sendaro

I used  my Lee Perfect Measure.  I checked about every 5th load   and it remained consistent  with 4759 and other bulky powders.   

No idea about question 2

Guys, Thanks for the replies, and info. I guess that it's trickle for the exact weight and that's it. Not a problem with fixed or per-load shells with wad + powder. Guess that I've been spoiled with Harrell's measures and 4227 and AA#9 powders. They make loading at the firing line in a match a cinch. 

With the recent development of new powders by IMR who know maybe they will come up with something to replace it with. I've been told that SR-4759 was dropped once before and then brought back. At any rate I've enough to keep me shooting for a while.

Why not sell it to some one who loves it and use something you are familiar with?

Frank, Your suggestion of mixing the many small cans together sounds like something that would work. However I have a un-opened 4 pound and a un-opened 5 pound. The only 1 pound I have is now nearly consumed. I'll give my B&M a try, and see how it does. The powder hopper was missing when I got it. Used copper pipe reducer, end cap and pipe to make the one in the photo. It work out with very little fitting to join the measure.

Have in the past had Bridging with both 4759 and 4350. An older poster GrampaXX years ago advised me to use a smooth small Rat Tailed File to open the hole where it necked to a Elongated shape just big enough to be seen. This cleaned up my problem and it has never re occurred with 4759. I no longer use 4350 but at the time it also worked there. HTH Regards, FITZ-G
PS. By the way 4759 has been discontinued at least three times in my shooting career. Always comes back. Think I know why. Found a Surplus Military Ammo dealer years ago selling salvaged 4759 at a good price. Six Lb Jugs for $4.00/Lb and discounted more if you ordered four at a time. Contacted him about his source. Reply was it was salvaged from .308 Blank Ammo. Used for Salute firing in M14 Rifles. Could make them function with just a Paper seal at the mouth of the Case. HTH

When I learned of 4759's demise I went on a quest to stock up on enough for the long haul. At age 64, I think I have it nailed. Since it's all in one and four pound canisters I think I'll dump it all into a clean bucket to blend it, and re-package in the original containers- that way I won't have to waste any of the precious stuff by having to reformulate loads sometime later on.

Since I'll be breaking the seals on the canisters, I'm thinking too of smearing wax around the lids for long term peace of mind.

I use it for most all of my .30 caliber cast bullet target work, and have found that measuring it via my old Belding&Mull (scale checking every 10 rounds or so) yields equal accuracy compared to weighing each charge. Not as accurate as with ball powders obviously, but practically speaking a no-brainer.
