Winchester 572 for 9 major

[Bakerjd]

Anyone used it recently? Or at all for that matter. I have 5lbs and did some research and it seems to have been used in the past but very little info I could find.

I've used it for major but in .38 super. Have seen it on nato reloading in their 9mm tests, haven't loaded any in 9mm but it was a good powder for what I used it for.

If you can get the velocity your after it should work good. I tried it on some lighter loads and it’s somewhat dirty, kinda like HS6.

Looks to be slower than the popular powders in 9 major (hs6, ac, cfe, 3n37). Close to blue dot on the burn rate charts I looked at. Granted those don't show by how much...

I used it in 9 major for a while, it worked just fine with the 115 grain bullets I was running at the time. 

572 is a less dense than HS6 or CFE/WAC, so major loads will have a bit more spillage when indexing (8lb comes in the big jug vs HS6 or CFE that come in the medium) 

in my gun 572 took about 1/2 grain less than HS6

572 burns clean more like CFE/WAC than HS6

 

I ended up changing to HS6 mostly because it was available when I placed a big order pre covid, I still have an 8LB I will open when I run through the HS6

Tried 572 shortly after it came out.   Charge weights were similar to Silhouette.  8ish with a 

115, 7.5ish with a 124, OAL 1.175.     Burned clean,  good dot track.  I would run it 9 major if

that was what I had.  I put the data in the book, along with data for 3N37, 3N38, N105,

Silhouette and AA7,   and went back to HS6.

Thanks yall. I'm currently running WAC but picked this up a while ago when powder was scarce.
