Came across some older cans of this powder, can someone please tell me what it uses may be?
Thanks greg

Fasteel, Odd this should pop up. I was just looking at an old IMR book. Are you sure it is 4756 or 4759? I always wondered what SR4759 was till I looked in this old book. I don't see SR4756 in here yet but would think it would be IMR???

Send me some, I was just wondering about trying SR 4759 when this popped up. I don't want a whole pound yet. I don't recall seeing it in shops but was probably there if they still make it. This book was from 95 when I tried a couple of IMR powders. I don't know if another company would have a SR designation too.

IMR had a few powders that were listed with an SR designation in front of a number.. SR indicated Small Rifle...

they were SR 4759, SR 4756 and SR 7625....

SR 4756 should not be confused with SR 4759....

Sr 4759 is a very flexible powder and is the slowest burning of the ones mentioned here...

Sr 4756 is better off in pistols, but is not so flexibly...

I can vouche that it does make a good reduced load in the 444 Marlin, as far as rifles go, and I have used it in the 30/30 with good results...

however it is not a bulky powder.. it will pressure spike easily...

you have to pay a lot more attention to what you are doing when using it, than a lot of other powders...

I don't recommend it for reduced rifle loads, unless you really are paying attention and know what you are doing.. it is much easier to double charge than Blue Dot ever was...

Keep SR 4756 for pistol applications only....and don't confuse it with SR 4759....

and the data IS NOT interchangable, regardless how close the two numbers are.. the powders burn rates are not...

Thanks Seafire, I was just looking at the book and didn't think 4759 looked like a reduced load powder. I just found 4756 in the handgun section. I figured it had to be an IMR powder with the SR.

it is a reduced recoil load, but not a reduced pressure load...

I use it quite frequently myself...

it is pretty accurate....

It works very well in 20ga. shot shells too.

SR 4756 is a hair slower burning than Alliant Herco and Winchester WSF and a little faster than IMR 800 and Accurate #7. roger

Hate to diagree, but grew up on Jack O'Connor who dated from these days, writing for Outdoor Life. The original Dupont smokeless was MR powder, short for "military rifle." The parallel for civilians was called "SR" which was short for "sporting rifle." Later, post WW I, the "IMR" line came out. Stands for "improved military rifle." As I recall and my hair is a bit thin, the SR's are double based flake powders. SR4756 was for heavy shotgun loads in 12 guage. Doubles as a magnum pistol powder. SR4759 was "close" which does not mean a thing as to data, to Herc (now Alliant) 2400. The other one, SR7625 was also a shotgun powder that doubled in handguns. Please find and use reliable data. PLEASE. Great product within its range of usefulness. Luck.

Thanks Ranger

I did get this powder from a guy that was a multigage skeet shooter that may have loaded some hunting ammo as well. FS

Fasteel, The only Load I find it in IMR Handloader guide is for the 357 Magnum (RIFLE) section. About all handgun, some 20 & 28 shotshell. Also 221 Fireball (HANDGUN). I only have 1990 & 1995 books.

Fasteel, if you are as your name implies part of the steel shot loading community than you'll want to hold on to that SR 4756 powder. It is an outstanding shotgun powder that remains more consistent than any I've used in sub freezing temperatures. There are Plenty of lead & steel recipies out there. Fast ones too. Even with Alliant Steel powder available, I still have several 10 & 12 ga. applications where I prefer SR 4756 over all others.

Well Roll Crimp there is no shortage of sub freezing temps up here in Alberta during the fall bird season.
I was the Kent sales rep for Alberta for a few years, I think I'm getting down to my last couple of cases of Tungsten Matrix, the best duck and goose medicine ever invented.
Do you have any 20 gauge data? Where can I find you 12 gauge data?
Thanks Greg

Fasteel,
Precision Reloading's Blanks To Supersonics manual lists 12 ga. in:
12ga - 3 1/2", 3" & 2 3/4" (Rem, Fed , Win & Active)
20 ga - 2 3/4" (Fed & Rem)
IMO, PRI published decidedly old school speeds under 1400fps in this much anticipated manual.

Ballistic Products has some Hevi-Shot recipies for Fiocchi in 12ga and in 20 for Fiocchi & Active. Also, BPI's " The Status of Steel" Handloading Steel Shotshells manual contains copious 12ga data in SR-4756 including Cheddite - you said you shot lots of Kent right? Kent & BPS Multi-Hulls are headstamped with the Cheddite stars aren't they? I really like Cheddite.

RSI's Steel Shot Shell Reloading Manual has a bunch w/ good speed including a 12ga 2 3/4" FGM load they clock 3/4 oz. at 1700fps (RSIG3405). I did not have any of their 20ga. SR-4756 recipes. Maybe someone else can help you if they have newer data.

Best if you order your own manuals, because from time to time I have noticed recipes mysteriously disappear with a subsequent update iteration. Probably a reason for that, huh? I don't update manuals every year as maybe I should. If you are going to pick one, I'd go with BPI (Ballistic Products Inc.) for 20 & 12 ga. for the wealth of SR-4756 load data & sales support.

I didn't notice that before but you are right. Nothing in IMR about Steel.

Roll-Crimp. I looked closer and there are loads in this book (1990) for 12 guage 2 3/4 and 3" also 16, 20, and 28 guage.

For steel shot you're saying - right?

No steel shot recipes found in the tan paper IMR "Handloader's Guide for Smokeless Powders" dated 7/99 that I have. Maybe just being the gun shop, counter-top, freebie they didn't want to include steel loading listings...?

Maybe you can help out Greg more with his quest?

No Sorry, NO listings for steel shot in my books. I just didn't see the listings for 12 & 16 when I looked through it before. The two books I have were the free counter books. I don't recall seeing any steel loads in any of those kind of books. I've never loaded steel only lead shot.
