W572 data information

[Nevada Ed]

There are a lot of new powders out there today and some are hard to find loading data for.

I had trouble with BE-86 and the new CFE-p powders when I first bought them to try out.

For those that might be looking at W572 ;

it is a very good slow burning powder, for the 9mm case, that will
give high velocities, at pressures that are within loading guide lines.

I have one "Net" source, that tested out this powder in several pistols
and used several weight bullets, in their test.
Here are some "Maximum loads" that you will need to work up to
to see if they are safe in your pistols, if you have to push the envelope?

This powder is a easy metering powder and 9.5 grs, almost fills the case.
Here is some of their data;

9.5 grs ...... Lehigh 65 gr ....... 1.10 oal .... 4" barrel ...... 1830
7.1 ........... Sig V crown 90 gr... 1.075 ..... 4.5" ............ 1475
6.0 ........... HAP 115 ............. 1.10 ......... 4.5" ............ 1295
6.2 ........... Delta HP 124 ....... 1.095 ....... 4.5" ............ 1285

These loads might not be safe in your pistols. Use caution.

Hope this might help out, if you buy this powder.
I will note that this company will be testing w572 in the future with "Major loads", for the 9mm case.

Ive found this to be a great powder for .38 standard and +P loads; .357 Mag light bullet loads and pretty decent in .45 ACP too.
I really like this powder.

Looks like it's close to AA7. I like powders that give good fill. Will keep an eye out.

Ed, you planning on testing 572 in 357/38 Spl +P?

It might work out there but "IF" I had some,

my first loads would be in the 9mm, to see if it might be the new
"King of the hill" for high fps loads, with lower pressures, than the
powders that are now known for top fps, but also high pressures.

It did look very interesting , in that one site, that listed only 20 PSI on a lot of the loads.

Of course. pistol types, recoil springs, camber specs etc, all toss a wrench into the mix.

AA#7 and HS-7 and W571 are and were all in the same burn rate range and yes, the newer W572 seems to be in the same class.

5.0 gr with a 158 gr bullet in a .38+P works great. 8.0 gr with a 125 gr .357 Mag works great , very clean powder.
