I know I've asked before ....
 

But is there a powder that in the forums re-loaders expert opinions takes the place of the 4756 and 7625 us low pressure guys were all so fond of ?

Unique is a good one.






.

Just pulled couple boxes reloads from shelf: 12ga 700-X pressure 7600/1145fps; 16ga Longshot pressure 7000/1175fps. Also 12ga 1 1/4 oz Longshot 6900/1185fps. I wouldn't use these reloads if I wasn't pleased with results!

I load 700x. 12 gauge @ 6000psi. Tested by Keith at precision reloading

Clay dot with the 3/4 ounce claybuster wad comes in around 6000 psi, but it doesn't smell nearly as nice as 7625 or 700x, especially in Federal papers.

Chris, just curious, what did you use 4756 for?

PB, 7625 and 4756 are/were single-base straight nitrocellulose powders and imo there are no substitutes for their desirable combination of relatively low pressure @ relatively high velocity, and with a slower recoil impulse @ the same velocity and with the same shot load than double-base powders that contain NG. There's more to it than burning rate. Also, so-called low pressure loads often equate to low velocity which is OK on a clays course but all too often means cripples when hunting. Personally I look for at least 1225 fps for hunting, and 1250 or more is better and I'll load one of the named single-base powders for hunting with vintage SXS's that are up to snuff.

It seems that 4756 and 7625 went out of vogue with modern reloaders and can still be found in out of the way gun stores where the jugs are often gathering dust. I understand that PB is still made, although tough to find.

Is this known to be true? It would be great for all of us that have relied on PB for our low pressure loadings, but goes against everything I've heard or read of it being discontinued.

Cold spring. You seem to really know about powders. Do you know of any powders available today that are comparable to 7625. Any info would be a great help. As I really like low pressure low recoil. Thanks for any insite you might have. See you in the field.

I got to thinking about low pressure and pulled out my paperwork on loads I've had tested. 15 grains of 700x. Under 3/4 oz shot. A 5 shot string tested avg. 4992 psi. @ 1182 fps. Not bad. You could always go up a little on the powder I guess. Lol I'm new at this . I hadn't been able to try it yet. As its summer in Texas and I been very busy. Hope this helps.
