Hodgdon HS-7... which is also discontinued, so Hodgdon's web site has not data.

stevespages.com has durned near every powder for every cartridge that it works in... it's just an aggregate of most of the data that's out there. If you use his data (and I have), tread carefully in the upper range. That's always good advice, but Steve seems to have access to sources that go beyond others that I've seen, in some cases.

It's a magnum pistol / heavy shotshell powder.

I use it for cast bullet loads in military rifles... a project that I'm just now starting.

Winchester 571 is an excellent powder for 10mm and other calibers in this range. If I was closer, I would buy it from you in a heartbeat.

Any reloading manual that's more than two years old should have load data for Hodgdon HS-7, which is the same powder.

Hope this helps.

Ya thats a lot of powder. I was hoping to do some 40sw, and 357. I will try to find the sources you guys suggested, thanks.

My OLD Winchester powder pamphlet says:

.38 Special +P

140-gr JHP (these were Silvertips)
Start 7.4 785 fps 14,600 psi
Max 8.0 890 fps 17,300 psi

158-gr JHP
Start 6.6 700 fps 14,100 psi
Max 7.3 800 fps 17,400 psi

158 LSWC
Max 7.7 910 fps 17,300 psi

.357 Mag:
none listed

.40 S&W--a whole bunch of loads, here are a few:

155 JHP
Start 8.5 1020 24,700 psi
Max 10.0 1180 33,200 psi

170 gr Lead
Start 7.0 900 fps 24,100 psi
Max 8.4 1070 fps 33,200 psi

180-gr JHP
Start 6.8 830 23,200 psi
==== 7.8 950 29,500 psi
Max 8.3 1015 33,200 psi

There are also loads for 9mm, 10mm, and .45 ACP.

The older book lists .357 loads with 630 and 230, but no 571 loads.

All cautions about typos apply. Use with caution. You're getting what you paid for.

Your local Public Library might have or will gladly order for you any older reloading manuals in their databases. (and many manuals are in library databases)

I would caution you that it would be a violation of copyright laws were you to then take that borrowed book to a photocopier or scanner and create pages for your specific calibers and put them in a 3-ring binder to have as a reference.

So please don't do that!

It was about 10 years ago. When Winchester announced it was to be discontinued, I called Widener's and bought all 22 pounds they had in stock. I'm hoarding it now..

Hey Fred
you must like 571 a lot, can you tell me what you use it with? I shoot 357, 40sw, 45acp thanks

It's the most accurate powder I've found for heavy bullets in 10mm, which I shoot a lot of. It will also work for .40 S&W, but I don't shoot a whole lot of that caliber. There are also some applications for it in .38 Super as well.

Hope this helps.

Fred,
Id 571 (HS-7) that much better than HS-6? I like HS-6 more and more every time I shoot it. I can easily see how you can feel the same about HS-7. (and even HS-5) I wish Hodgdon wouldn't have discontinued them.

I use it almost exclusively for 180 grain and 200 grain bullets in the 10mm. I've got other loads, with other powders, that will drive these bullets faster, but none that are as accurate out of my 10mm handguns.

I've never tried HS-6, so I don't know how it would do with these bullets. To tell you the truth, I found the loads I use in Handloader Magazine several years ago, and they worked so well, I never tried anything else.

Thanks for the info. I agree, if you find something that works just as you want it to, why mess with it...
