The SR#### Powders


January 23, 2007, 12:33 AM
I stumbled onto SR4756 when a too good to pass up deal fell in my lap. Wasn't sure how I'd use but I began expirementing. Soon it was my favorite powder for 45 acp due to it's clean burn and accuracy. It didn't do too bad in 45 colt either for moderate loads, 255 gr @ ~850 fps produced sub 2" groups in my RBH @ 25 yards.

Next I tried SR4759 for cast loads in my 45-70. A little goes a long way when you use less than 30gr the big ol' 45-70 case. Not ultra velocity but for loads ~1500 fps it was perfect and is THE most accurate and cleanest burning powder I've tried. Ended up buying a keg of it.

Today I visited the local gun shop and the owner was talking about SR7625 and how well it performed for him. Well, if was a ploy to get me to buy some, it worked! Got home loaded up a bunch of different 45 Colt bullets and charges and we'll see how it does.

Anyone else use the SR powders?

I've used SR 4756 for .38 Special and some .45 acp loads since about 1965 or so. It's a really good pistol powder, but doesn't get much attention. SR 7625 is my favorite 9mm powder, but I'm loading a recipe that isn't in the manuals. It meters well and like you pointed out, clean burning. It's also accurate with plated bullets.

Hope this helps.

SR is short for shotgun reloading or shotshell reloading. The powder is primarily used for shotshells, and for over 40 years SR4756 has been my favorite powder for 12ga 3" 1 5/8oz magnums.

For 9mm, 40S&W, and 45ACP target loads, I found 700x to be much more economical and accurate. The 800x is my favorite for most heavy bullet high velocity loads.

I have some old Dupont SR 4759. I thought IMR took over all the Dupont stuff.

SR 4756 provides good accuracy with standard velocity 9mm loads with 115gr and 124gr bullets. It also burns with a nice aroma.

Charges below 4gr. metered very inconsistently in my RCBS Uniflow.

SR 4756 was one of the first powders I used when I first started reloading. Works very well in a lot of cases. Kind of hard to find in my area at times and a bit more expensive so I went to other powders. About a year ago a friend gave me a 1 LB can that I haven't used yet but will in the near future. One friend uses 7625 for some cartridges and 4227 for magnum loads.

I bought a 5 pound can of 4756 for loading steel shotshells. Then along came Alliant STEEL powder, I didn't use the 4756 anymore. Then I became interested in IPSC, bought a Glock M-22 and started loading 40 S&W. I was looking through loading books for a load for 165 grain west coast plated bullets. A load for 4756 caught my eye, I tried it! First time the first load worked well, as for accuracy and velocity. Took about a year, but I burned the whole 5 pounds of it!:rolleyes: Problem is to replace it, it's one of the most expensive powders out there!:mad:
