WINCHESTER 572
 

I was wondering if the Winchester 572 powder is popular with any folks here. I have been using it for the past six months in some low pressure/velocity 2 3/4" 20 and 12 gauge loads. It is becoming my go to powder for these type of loads and it is readily available to purchase.

I got an 8 pounder maybe four or five years ago and tried it a bit if my memories correct in the 12 or 20 and then set it on the shelf . Acquired another 12-16 pounds in one pounders about three years ago which I’ve since passed on to someone else . Anymore about all I load is 10 gauge and I saw the load Victor sent to Armbrust for pressure testing and have tried it in that capacity . At some point I may use it in the 10 but I have a bunch of other options to use up first .

I think it is suited for 12 and 20 and even 28 Ga low pressure loads.

If I’m not mistaken Hodgdon’s has 10 gauge 2 7/8” loads using 572 in the load data .

Here’s it tiz .

They show data for the short 10 so if it’s good with down to the 28 then it must fall about the same general area as SR7625 , Unique and Universal Clays as I’ve used them in everything from the 10 to the 28 .

I’m sorry I spoke incorrectly about the loads Victor had posted for the 10 . He was using WSF . https://parkerguns.org/forums/showthread.php?t=23362

Winchester 572 is intended ideally for 20 and 28 gauge loads, as well as several handgun loads. It has worked satisfactorily for my 20/28ga. reloading, albeit not as clean burning as International or Universal. I'm glad to learn that it's also suitable for some 12ga. 1 oz. loads with the components I typically use and have on hand -- I just wish there were some tested load data for 12ga. 7/8 oz. loads.

Greg using the Hodgdon Reloading Data Center I came up with four low pressure, low velocity 1 oz loads for it. The pressures go from 5,400 PSI to 6,900 PSI.

Yes, I've seen that data, but like I previously mentioned some of us would like to see some 7/8 oz. 572 load data published as well.
