Different powders. Winchester 571 became Hodgdon HS-7, which is now discontinued, which is a shame. It was one of my favorite powders for .38 Super and 10mm.

Hope this helps.

Sounds like a non-canister surplus powder. Do sellers offer any load data? Call Hodgdon and ask for information.
 
Thanks Fred!

I was kind of thinking of how Winchester replaced W230 with W231. Thinking maybe they could be doing the same, making W572 to replace the old W571.

Question, was HS-6 a replacement for HS-7?
 
HS-6 and HS-7 were also two completely different powders, with HS-6 still being in production. I'll go through some of my old manuals and see if I can find any reference to the powder in question.

Hope this helps.

HS-6 is the old Winchester 540 powder, and HS-7 was the old Winchester 571. I looked in Wolff Publications "Propellant Profiles" and there was no mention of a Winchester 572 powder and I can't recall ever hearing of it. None of my older manuals mention it, either.

Just for information, the Ramshot Silhouette powder is the old Winchester Action Pistol (WAP) powder. Both Winchester and Western powders list identical loads and pressures for those powders in their manuals for the 180 gr. 10mm.

I have an 8 pound keg of Winchester AAP, which was also known as AA Plus, and was only available to the public for a year or so. It's the powder they used in their factory AA 12 ga. trap loads. They mention in the only manual they had any data for it that it would be a great handgun powder, but they never published any data in handgun calibers, only shotgun loads. I'm going to work up a load with that powder for .38 Special, just so I can use it up.

Hope this helps.

Fred, thanks for that info. I didn't realize HS-6 is the old W540.

rg1, Bing and Google searches only came up with the links I pasted above. Thanks for the link.
 
Curiosity got me to call Hodgdon. The guy I talked with said the powder is for shotgun/handgun. And it should be shipping in 2-3 weeks. And that they will be updating the reloading section of their site shortly. As for burn rate, he said it is slower than W231.
 
The link didn't work, so I copied and pasted the information on the link:

572

This new Winchester powder is strategically designed to do a myriad of jobs. First it has the correct burn rate to create the famous 3 ¼ dram equivalent, 1 ¼ oz, 1330 fps 12 gauge load, originated by Winchester. And, it does it with any brand case! Back Fence competitors and pheasant hunters will be delighted. Now, that is just one application, and it goes on to provide clay target loads superb in 20 gauge and 28 gauge, top field loads in both, and, outstanding field loads for the wonderful 16 gauge. In addition, 572 has a vast number of pistol applications, ranging from the 25 ACP to the 45 ACP, and all popular calibers in between. This is one positively versatile and useful propellant.
 
I'm curious what the handgun data will look like. They're discontinuing SR 4756, so I wonder if this is the replacement? If so, it will be a pretty versatile powder.

So far, Hodgdon has only posted load data for 12 & 20 ga. Nothing that I see for any handgun cartridges yet.

What has me wondering is, this powder shows up with no fanfare or announcement. Not even a search on the web reveals any hint from gun mags or blogs.
 
I was in the Hodgdon booth at the SHOT Show in January, but we were talking about old times and how the company started, etc. I should have paid more attention to what they were offering in the way of new powders instead of talking about Bruce and CB Hodgdon......

Fred
 
I too am a big fan of the old HS7/571 powder and was hoping that 572 might be a modern update. Not so.

I compared the new Hodgdon load data with old HS7 and 571 data from the 80s and 90s - there appears to be no overlap at all concerning charge weights. Performance in same calibers/bullets is quite similar, but the new 572 charge weights are quite a bit lower than the older powders.

In the end, this new powder might fill the same roll that the older ones did, but do not even think about looking at old load data for guidance!
 
Mauser69, that is good info to bring up. I found some W571 data for 40 & 10, but haven't compared them yet.
