New Winchester Powder

Winchester 572

Hodgdon Powder Company announced the release of Winchester 572: a new powder for the loading public. The new 572 began showing up on retailer websites recently, and the company made a formal announcement last week about it.

While a lot of details are not yet available on 572, the company states the new loading powder is designed to work well in a variety of loads. One of its main uses is as a shotshell powder.

According to Hodgdon, this load allows shooters to perfectly duplicate the Winchester AA target load in 28 gauge and the 12 gauge upland game load loaded with 1.25 ounces of shot at 1,330 fps. The company also states the powder is a good choice for handgun loads such as .380 ACP, .38 Special, 9mm and .45 ACP.

The powder will be sold in one, four and eight pound containers.

According to some folks at Cast Boolits that have gotten their hands on it, the powder is a ball powder with a burn rate similar to that of the IMR SR 4756 powder. Additional information can be found in the April 4 episode of the Power Factor Show.

Hodgdon will have load data available for the Winchester 572 powder on its reloading recipe site At the time of this writing, some load data is already listed on that site.

    Slow-burning in pistol calibers? I wonder if it could be used to make enhanced carbine-specific loads for PCCs.

    • iksnilol

      I think that’s the point.

  • marathag

    Still would have been nice to know where it fits in by burn speed, like is it really as slow as the old Herco, 800X or 540 Win, and faster than Blue Dot or 571 Win.
    That said, I welcome more ball powders

    • Mark Horning

      Probably slightly slower than Blue Dot if it is being recommended as a 28ga powder.

  • Fargo007 .

    Yeah, because we’re just fat as hell here on Varget and H4350….. Please do keep spending time on boutique shotgun powders.


    • Christian Hedegaard-Schou

      Hodgdon doesn’t make any powder. They repackage and re-sell mostly St. Marks and, I believe, ADI.

      If you have an issue with not enough Varget, you should be mad at the OEM, not Hodgdon.

      • Fargo007 .

        So… If I buy a dozen eggs at a supermarket and they are rotten, my problem is with the farmer?

        I don’t care who their supplier is.

        Hodgdon is the powder company. If they put their name on the label, that’s who I address the issue is with.

        • Christian Hedegaard-Schou

          What you’re saying is, if there is a nationwide shortage of eggs you’re going to be pissed off at Safeway for not being able to get eggs, even though you can gets apples, oranges, and milk?

          Because that’s what this is like.

          Yes, be angry at the farmer for not being able to produce enough eggs, not safeway for merely distributing them.

          • Fargo007 .

            Are you in Russia?

            If I ran a supermarket and had no eggs and a customer complained, according to you, should I have him take it up with the individual farms I have been buying from?

            That’s what this is like.

            My supermarket would be out of business in a week if you were my customer service manager.

      • David Underhill

        ADI here in Glorious Australia make VARGET and several other Hodgdon branded powders. St Marks makes the reset.

    I would like to see a powder developed for 5.56/.223 subsonic that does 80% or more fill with 55gr. projectiles. I’m using Trail Boss with 75gr. BTHP and 4.7gr. gives me 1040FPS, but the fill is 63% so have to use cotton wadding. It is even worse with 55gr., 3.3gr. with 40% fill and I just cannot get any consistency with that low a charge.
    Why, you may ask, do I want 5.56 subsonic? Fun Factor with my suppressor. Silent varmint shooting, or target practice with no ears.

    • Jwedel1231

      I know that empty space inside a case is bad, but why exactly?

      PS, have you tried using a larger (90+ gr) .224 projectiles?
      PPS, that’s a sick AR you have there!

      • Paul Epstein

        Empty space means that the powder moves around and tends to pile up in an unpredictable way- sometimes it’s all towards the front of the case and the primer doesn’t set it off, or sets it off later than expected, causing a hangfire. And it’s possible with a lot of empty space in the case to get detonation rather than deflagration- instead of the powder burning, it *explodes*, ruining the gun and potentially hurting the shooter.

        • Geoffry K

          You got it. All the info I could find says to pack the empty space with spider-webbed cotton and gently tamp it like wadding.

          • itsmefool

            In an old issue of some gun rag in my collection, there was a sweet story about the .458 Win. Mag….when the author, a reloader, had empty space in his case, he filled it with cream of wheat! I’m thinking that’s no longer approved! First I heard of it, but it seemed to be common back in the late ’60s and early ’70s, at least.

          • RMP52

            Cream of wheat was, and is, an entirely acceptable filler. Kapok was another great filler, if you can find an old Mae West life preserver, you would have a lifetime supply of kapok.

          • LG

            I have used a lot of cream of wheat before Trail Boss was developed. Cream of wheat can compact and solidify into a hard “slug” which can spike pressures. Kapok and puff-a-lon work better. Puff-A-Loa is excellent but with Trail Boss there is no need for it.

        • ostiariusalpha

          That’s a very good explanation, though with a reduced powder load your chances of getting what is called an SPS (secondary pressure spike) are far more likely than a true SEE (secondary explosion event, i.e. detonation); an SPS is nearly as dangerous, as it will rupture the pressure vessel.

      • Geoffry K

        I did try Hornady 80gr. A-MAX, but I had to cut off the red tip so I could load them in a magazine. They worked pretty good. Needed 4.8gr.
        I built that AR from scratch. Ares Armour 80% aluminum lower, PSA SS 16″ 1:7 barrel, PSA upper and full auto BCG, MagPul MOE stock, 15″ free float quad rail I found on eBay for $35, UTG Bipod from Amazon, Bushmaster LPK, Millet Tactical scope mount with a 20mil shim, Nikon P-223 4-12X 40mm. scope and Form 1 registered MagLite style suppressor. I use a SS tube from Apogee Products and the end cap and thread adapter from SD Tactical. Dorman expansion plugs from NAPA. Did it all with just a drill press and cross slide vise.

        Too bad I can’t post the video I made shooting the subsonics. No Google+ or YouTube or anything like that.

        I already submitted another Form 1 to ATF 5 weeks ago for a 30 caliber reflex suppressor. Saving up to buy a Grizzly Metal Lathe while I wait on the approval.
        Going to use it on my also built from scratch 300BLK.

        • Jwedel1231

          You ought to get a YouTube channel, some of the things you wrote out would be interesting to watch.

      • Geoffry K

        90gr. would seat too far in the case to get 2.260″ OAL, it would put the ogive inside the case. Seating to proper OAL would mean single round loading. Would be OK for a .223 bolt rifle though. (Yeah, I tried it. Not good. Bullet engaged the rifling, pressure increase)

        • Gorilla Biscuit

          Depends on the ogive. This is a 100gr 5.56 projectile seated to mag length.

          • Geoffry K

            That might work. The ones I thought would work were
            90gr HPBT BULLET (VLD-TGT).
            Obviously wouldn’t work after I tried seating to 2.260″.

    • LG

      Fillers are not used or recommended with IMR Trail Boss powder. It is fast burning and relatively position insensitive. That is the reason it is so goo in blackpowder cartridges such as 45-70 and 45 Colt.

  • USMC03Vet

    Looks like a supplement.

  • Fargo007 .

    We’ve talked of business, marketing, and customer service. We understand these things very differently. That’s why I asked if you were in Russia, because your suggestions seem born of a foreign mindset and would fail spectacularly.

    I don’t believe you are aware of the long range rifle powder situation, and how ridiculously long it’s gone on for. It has been several years.
    It needs to be fixed. They own the brand, so it’s their issue.

    • gk.price

      sounds to me like you should find another SUPERMARKET ! I have plenty of Varget and could buy another couple of pounds after breakfast if I needed it ….. there are also plenty of other powders that fill that niche

  • smartacus

    wow! 23 comments and no mention of W231 or HP38 🙂

  • itsmefool

    My only problem with today’s powders are the names…I’m quite shocked they haven’t gone all “tacticool” like seemingly everything else! How about “Blockbuster” for a name? Oh, wait…
