Winchester 572 Powder

[[email protected]]

I was checking out Midsouthsouths Shooters Supply's inventory on powder earlier, and I noticed they had Winchester 572 powder. Well I never heard of this powder before, so I went to Hodgdons site to check it out. It sounded good after reading the description, but I couldn't find any load data for handgun rounds on their site though. It's also not listed in their burn rate chart. Anyone tired it.

From the internet... Jan. 2016

" Thank you for your interest in IMR. Unfortunately all the SR powders including 4756 was discontinued the end of 2014. We will be introducing a new Winchester powder called 572 that will be similar as 4756 in 12, 20,and 28 ga field and target loads. Winchester 572 will be introduced in March and on the market soon after.

From Winchester's Powder page...

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.

Can't find any data.... yet.

It's brand new and they're working up some data for handgun use. They'll post it on their website when it's done.

Hope this helps.

Powder Valley has been showing W572 in stock for about 1 1/2 weeks now. As Fred said, Hodgdon should be posting data any day for handgun. They have the data posted for shotgun.

I got a feeling that W572 will be along the line of Universal. But I have been wrong once or twice.

Hodgdon Reloading Center posted W572 data for several handgun calibers. Starting with 380 up to 45. Looks to be on the Autocomp, CFE Pistol, and Universal range.

No .357, 10mm, 357 Sig, 44, 45lc, etc. Seems to be more like it advertises for shotty and common carry calibers.

They only uploaded the data yesterday. I believe there is more to come. Seems they started with the more popular cartridges.

Maybe, but it will be a plinking load for low to mid velocities for the larger case calibers if so being that its a fast burner. Not that that's a bad thing either.

I found the load data update yesterday. I compared it with CFE pistol and WSF. It didn't do anything they didn't do in the calibers I looked at. I guess its "special" and "needed" because its a ball powder.

A quick scan of the data looks as though W572 will do better with the heavier bullets.

It looks very close to WSF. Since I have 2 big jugs of WSF I'll hold off on the 572 for a while. CFE appears to be slower burning at .40 pressures with 180 grain slug. CFE is very accurate for me in 10mm plinking loads with 200 grain slugs/7.0 CFE so I'll hold off some more on the 572.

looks pretty close to AutoComp

I'm just wondering if W572 is going to be similar to W571/HS-7 in handgun cartridges? I kinda liked HS-7 although there are plenty of powders out there not that do the same job. If it is similar I'm betting the 40S&W/10mm loaders will like it.

 

[ReloaderFred]

Hodgdon says it's closer to SR4756 in performance. I've been working on a 12 pound keg of SR4756 for quite a few years now, and when it's empty, I'll probably give the Winchester 572 a try. Being a ball powder, it should meter really well, though I've never had any problems metering 4756, either.

Now, if they would only find a direct substitute for 800X that would meter well..........

Hope this helps.

To me it seems like there's a lot of overlap between this powder and others that are currently available from Hodgdon/Winchester. I'm betting this is one of those new powders that's supposed to be easier and faster to manufacture. It might be replacing something within the next 5 years if it becomes popular.

I see that the online Hodgdon load data now contains data for Winchester 572.

Looks like they have pistol data for: 9mm, 40s&w, 357sig, 45acp, 380auto, 38super auto

Maybe it is cleaner and cheaper to make than some of the existing powders, as mentioned in the 231 scare.
