Keola5o4 Posted November 5, 2016 Share Posted November 5, 2016 Anyone still running this powder through open guns for 9 major or 38 sc? If so how the research going on it? My local store just got some in and most likely getting a pound to try out also. Link to comment Share on other sites More sharing options...
Jimboslice Posted November 5, 2016 Share Posted November 5, 2016 I've ran it for about 5 months in my 9 major gun and like it a lot. It's also pretty clean. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

js1130146 Posted November 6, 2016 Share Posted November 6, 2016 Ooop sorly about that. Dunno how I missed that you were the same person... Is it clean? I'm currently running HS6 but it's so darn dirty. Seems like 572 might be a touch faster as well Link to comment Share on other sites More sharing options...
Jimboslice Posted November 6, 2016 Share Posted November 6, 2016 No worries I've done it a few times too. I haven't ran a whole lot of HS6 but I can tell it's cleaner and has a drastically different recoil impulse.

I was about to buy another big lot of hs6 but I might have to give 572 a shot first Link to comment Share on other sites More sharing options...
Keola5o4 Posted November 7, 2016 Share Posted November 7, 2016 Got me my first pound today, fixing to work up a load. I'm coming from using 7.9 grains of hs6 with a precision delta 124 9mm major going through a 4 port Schumann barrel. So this should be interesting Link to comment Share on other sites More sharing options...

Bamboo Posted November 8, 2016 Share Posted November 8, 2016 I got a pound of this recently, also. The initial reports were that this is the replacement for SR4756, but it seems to be a lot different as far as density, powder type (flake vs flattened ball), and published and anecdotal load data. I'll be working up some loads for 38 super and will report back. I still have some 124gr SR4756 rounds loaded, so the plan is to work up a load with the same bullet to the same velocity and compare side by side.

Keola5o4 Posted November 9, 2016 Share Posted November 9, 2016 Had a chance to do some load development, I was using a Dillon 550 to load these. I was getting inconsistent powder drops for this particular powder compared to the cfe and hs6 sometimes 1 to 3 grains off "not sure it makes a difference" so I hand loaded them with a single stage press.Made 10 of each load and ladder up, these are the readings off the competition electronics chrono.Shooting out of 4 port Schumann barrel with win 572 and precision deltas 124 grain hollow points1st string.7.2 grain load 1345fps average pf 1662nd string7.5 grains load 1349fps average 167pf 3rd string7.7 grains 1355fps averaged 168pf Recoil through the gun was not violent and was very pleasant to shoot. The dot tracking was almost like shooting a minor load with a loud bang. "That being said"I'm gonna attempt to load up to 8 grains or alittle beyond over the weekend but it seems the power factor is a little close to major borderline for me but I'm gonna keep working with it.

Keola5o4 Posted November 9, 2016 Share Posted November 9, 2016 P.s the chamber of the gun didn't get all gunky as the hs6 I used to run, even with only 10 shots it got pretty nasty. Link to comment Share on other sites More sharing options...
user293 Posted March 11, 2017 Share Posted March 11, 2017 Anyone got any updates on this powder in open guns? Link to comment Share on other sites More sharing options...
Wheeljack Posted March 12, 2017 Share Posted March 12, 2017 I am always amazed by how the powder industry works so hard to confuse the buyer. Ball powder is a trademark of Winchester. Win 231 is ball powder. Hodgdon HP-38 is spherical. They are the same powder. Nowhere on the Hodgdon container does the word spherical appear. If you search you can find that Hodgdon does call it spherical. Why does my HP-38 look like flake powder? The new Winchester 572 is out. It's a ball powder. Hard to find any information on Sport Pistol powder, but what little I have seen, it reminds me of Win 572. I won't even go into how books like Lee's Modern Reloading tables show how hard manufactures work to prevent us from being able to compare powders to each other. I don't know if I should get mad or enjoy the challenge. Don't you wish we could buy 1 oz test size packages of powders? Enjoy. Link to comment Share on other sites More sharing options...

Sport Pistol initial loads 010217.pdf It's close but still hard to pin down with all the different bullets and COAL's. But in the ballpark. Hodgdon has data for the 572 on line. If Winchester Ball (spherical) powder is round, then why does the 231 (HP-38) look flat like flake powder? Corporations lie.

pbairborne Posted March 13, 2017 Share Posted March 13, 2017 I did a little load development for 9 major. My open gun is full length with no holes. All my loads were 121 Montana Gold IFP's loaded to 1.175 with 0.377 crimp and Tula Small Rifle primers. 6.0 grains W-572 gave 141 PF 6.3 grains W-572 gave 151 PF 6.6 grains W-572 gave 154 PF 6.9 grains W-572 gave 161 PF 7.2 grains W-572 gave 165 PF 7.5 grains W-572 gave 168 PF I didn't see any pressure signs. Seems just a little slower than AC or CFE Pistol to me. Link to comment Share on other sites More sharing options...

pbairborne Posted March 14, 2017 Share Posted March 14, 2017 Sorry to say I really haven't taken the time to do comparison with other powders used for 9 major. Maybe when I get back to Ohio in another month or so... Link to comment Share on other sites More sharing options...
racer-x Posted April 2, 2017 Share Posted April 2, 2017 Anyone have updates on 572 as a major PF open powder? Curious how dot tracking is compared to WAC, HS-6, 3n38, etc.. Link to comment Share on other sites More sharing options...
Jimboslice Posted April 4, 2017 Share Posted April 4, 2017 I still haven't really done a thorough comparison between 572 and any of the others but I really like it. It throws well, has decent case density and I don't have to fill the entire case to make major with 124 gr MG jhps.
