47SL surplus powder

Use H414 or Win. 760 data. 47SL is very close, ( some say "interchangeable") but as always start a bit light and work up.
Very versatile powder with a wide range of applications.
 
Hi-standard; I have burned a couple of dozen pounds of 47SL [lot 10] in many chamberings, and still have a quantity of it in stock. It is a great powder, that, in my experience, is just a bit slower than W760/H414. Perhaps 1 - 1½ grains slower, which makes it so close to IMR 4350, that it isn't funny. It will give good velocities and superb accuracy in the 30-06 behind 165's or 180's, but I consider it a tad slow for 150's myself, but usually accuracy is still great, but velocities are not as high as some other powders give with this weight. Start at 54 grains with the 180 and work up. I shoot 57.5 grains in my 700 SSDM for 2750 fps and groups under ¾ moa. I also use a couple more grains with the 165 and usually cut one ragged hole at 100. This true sperical powder works like magic in a powder measure and flows so well. One word of advice. It is good to take some fine steel wool and clean the case necks of the residue right after you fire each round. The residue becomes very difficult to remove after being on the neck for several days.

I love that powder. 54 grains of it behind a 180 grain bullet is all I ever load in my 30-06. Accurate is an understatement. Velocity variation over a chronograph are so minimal that if I write em here I'll get called a lier!

Is Higginson selling more of this?

Is Higginson selling more of this? Is it still 7 bucks a pound if you order a bunch?
 
Unfortunatly Boys, the supply has dried up.:( If I had my time back, I would have bought a lot more. Higginsons has very little of anything left in surplus now. Who manufactured 47SL anyway, was there another name on it? Bought some N-69 for my 44 and 357, I find that stuff pretty good. Don't suppose you can use that stuff in non-magnum rounds? Or will the pressure be too low to burn?

According to Hi-Standard, no. However, for $4.50/lb more Hodgdon is still making H414, and it meters at least as well, and is perhaps even more uniform lot to lot.
 
Since there only was one lot # from Higginsons [Lot # 10] of AMS47SB, the variation is a non-issue. This stuff is really consistent, I'm pleased I laid in a few 7#ers before the stock dried up. I originally bought 21 pounds at $8.00/lb. Another one that really shone in 30-06 and similar offerings was 47N, [AKA HP 104] a Nobel powder just a little quicker than IMR 4350, extruded, fine grained and very clean. I used a lot of it in 220 Swift and 7x57. Also worked well in the 30-06 up to 165 grain pills. I had pretty good luck with another lot of Olin ball powder as well. Higginsons marketed it as W760 [SL #131]. It was a bit slower burning than 47SB lot 10, and worked well with 30-06 180 grain bullets. But the stock dried up several years ago now. Regards, Eagleye
