Sr 4756?

[Bert2368]

Just found an lb. of powder labeled "Dupont 4756" in a box of stuff I was given. But it's in a mason jar, not a factory package. It looks like Bullseye- I've never used any of this before, what should it look like?

It's a flake powder around the speed of unique. I use 4 grains behind a 358477 boolit in 38 special.

It looks pretty much like B'eye.

Thanks guys- I'll proceed with caution...

If you need data for 4759, it's around. You can PM me with specific needs. Regards, Woody

SR 4756 is a great pistol powder. I've been using it since about 1965, when the owner of a reloading shop (yes, there were shops that specialized in reloading back then) told me about it and suggested some loads. I've been using it ever since.

At this particular shop, you could bring in your own container and he would weigh out whatever you wanted from the 50 pound drums he kept in back. I always took in coffee cans. Perhaps that's how the powder got in the Mason jar...

Hope this helps.

I use SR 4756 for loading "lower-than-most" pressure loads in 10 gauge 2-7/8" shells. This powder was used in a series of loads that were pressure tested by a guy named Sherman Bell in the "Double Gun Journal" for loads in older 10 gauge shotguns. It is also useful in 20 gauge and as others have already posted, handgun loads.

Not to be confused with SR4759-which is a completely different powder.

My first project will probably be .45 ACP for a 1911 using the new Mihec H&G #68 SWC clone. Data I've found suggests 7 gr or a bit more... Anyone loading cast for the 1911 with this?

He did say 4756. Is is an easy mistake to make. Two very different powders.

Maybe this is why it is a good reason I don't use either one?

Absolutely, very different powders. I use 'em both, and I knew he was asking about 4756. My answer to his question was for 4756. Yet when I typed a followup, I typed 4759. Duh, musta been a senior moment! Regards, Woody

4756 was intended originally as a shotgun powder, but it found a wide following as a pistol powder due to its versatility. It works well in the 45ACP, the 38 spl. and the 357 Mag. I use it in the 44Mag for 25 yd target with 9 grains behind H&G #503 and the recoil is mild; burns clean and is accurate. Another favorite use for me is in the 9MM, primarily with my Luger. With a 115-120 grain roundnose and 4.7 grains it has low recoil, burns clean, runs the action, is accurate and does not batter the pistol. I have used it successfully for many years. It undoubtedly has many other working applications in many other cartridges as well. LLS

Sounds like you got a free can of lawn fertilizer, to me!

I'm with Gear on this one. Unless you can be certain of what it is or work up assuming it is bullseye with a chrony until it proves slower than bullseye, I'd feed the roses with it.

Starting with 7gr only to find out it is BE in a jug marked wrong would be potentially catastrophic to you and the gun. If you have any thought that it might be something other than as marked, be safe.

No way I would use it. Powder is cheap compared to surgery.

What he said. Period.

SR-4756 is THE powder for 32-20 WCF revolver applications, FWIW.

I absolutely hate to throw anything good away!

SR 4756 is a very good power!

A powder in a mason jar is a pretty scarry situation .......... they might be throwing your once fine 1911 away and hauling you off!

Better to feed the roses and let them sort it out!

Best regards and be safe

Agree on the safe disposal suggestions.

But FWIW....works really good in my 4" S&W Model 58 .41 Mag with H&G 210-grain Keith type pb cast bullet.

Also 13.0 grains with a 200-gr. cb in a 1903 Springfield 30-06 shoots well.

One pound of powder doesn't make the risk-benefit ratio even close to worth it. See my avatar - not a mis-labeled powder, but a reloading error. Eliminate EVERY possibility for an error - this is an easy one to eliminate, make the flowers prettier or use it as a demonstration that smokeless gunpowder isn't explosive unless contained, aka, burn it in a pile.
