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.

Make some up and send them for testing. If 1 oz loads fall between 5400 and 6900 PSI, I'd bet that the 3/4 oz loads would fall in a very similar range.

You can. safely drop that load to 7/8 or even better 3/4oz. You can thank me later.

What do you load in the 28 , 5/8’s ounce ? :whistle:

Nope, standard 3/4oz 28ga load, 1150-1200fps.

I am a little surprised that nobody has asked where to find a bushing chart for Winchester 572 because it is not listed in the official MEC bushing chart. Hodgdon has their own MEC bushing chart and the MEC bushings throw same number of grains for both Longshot and Win 572 but the two powders are not interchangeable as far as I know.

I’m in the process of loading a box of 10’s with 572 . Did have to make some deviations cheddar cheese hulls in place of Federals , cheddar cheese primers in place of Federal 209A’s and a 3/8” wad in place of two 1/8” cards . Didn’t bring a 10 to the shop so I could test a couple in the snail so that’ll have to wait until I go home and trim a tree limb or two . Also using a #27 bushing is maybe a 1/4 grain under what the Hodgdon recipe says .

You can make fun of Cheddite if you want to but if it hadn't been for that company we would have gone several years without any 209 primers to buy.

That may very well have been the case for the vast majority but I’d already started stockpiling when the Obamite was you guys so called president .

That's great but who is "you guys" and why are you bringing politics into this thread?

Shot four of them in an NH 34” that weighs about 10 1/4 pounds with a nice KickEez on the back . They felt quite comfortable and took down a pair of rather stout (about 4” diameter ) limbs that were up a bit on the high side .

That’s not politics that my distaste for that so called human . You guys is anyone that isn’t me and cared to use the title on it .
