Winchester 572

[Elpatoloco]

Anyone use 572 in handgun calibers?

Local Hardware store bought into the Craze of the last few years trying to cash in. This stuff has been on the shelf for 3 or 4 years. Everything has always been outrageous like $175/brick on primers. $60/ lb on powder.

I went in for an Air filter for the A/C today
They had the 572 on Clearance today for $23/lb.

I bought the last 6 they had. Folks were carrying it to the register by the arm loads

I read somewhere
replaces WW571/HS-7
both similar to Bluedot
I was going to try a pound, then they went nuts with the price, went to 300MP

I didnt find a load in .357 or .38 that the Blackhawk didnt like. I'm not pushing for Maximum Velocity or anything of the sort. Have bigger guns for bigger jobs. I dont care for the shorter grip on the Blackhawk vs the Supers. I may have to contact Ronnie Wells for a proper grip frame. Didnt chrono anything, but the 572 works well enough.

I am a huge fan of ball/spherical powders, but have never tried the WW 571 or 572. I always saw them marketed as shotshell fuels, and the spherical powders don't get along with my MEC loaders very well. If they run in the Blue Dot playground area, they should be right useful as handgun powder.

it's been the hot deal for 20 and 28ga. recently.

I bought 3# of 572 when Brownells had a good sale on it back in 12/22. I had been using a bit of 244 for mid-range loads since I couldn't find Unique, and knew I liked the new WinClean powders. When Brownells had their sale, I saw the 572, looked it up on the burn rate chart, saw that it was close-ish to Blue Dot, so I grabbed some while I was ordering more 244. After I started looking at the load data for it, I was very, very surprised to see that all of the published load data for .38, .357, .44 Spl and Mag, .45 Colt and ACP has it doing no better than 244 but taking a bit more to do it. I'm a bit perplexed by this. It seems that, based on it's burn rate, it should get a bit more performance than that.

It seems that, based on it's burn rate, it should get a bit more performance than that.

Burn rate is not a good predictor with shotgun/handgun powders. It has to be overlaid with rate of rise of pressure. Rate of rise is not liner, but curved. Heavier loads greatly increase pressure with smaller increases of weight. Some like SR7625 are nice and smooth until about 15,000 and then go up really quick!

Herco doesn't do anything Unique doesn't with do with 7% less .

 

[fiver]

unless you put it in a shot shell.

gotta remember that pressure rise thing Ric was just talking about.
they might be equal in the book but the when and for how long isn't.

When Hercules was still in business, pre-Alliant and pre-internet, wrote letters to a guy in their tech department. He said that they never tested shotgun powders over 20,000 CUP. Powders that had "pistol" on the label was 24,000, unless listed was magnum and them went to 40,000. They used the old Potter pressure action with SAAMI barrels.

In my old age, I am careful about what I load and never steer anyone to over powder company data. Why I keep old reloading manuals.

I pretty much stick to books loads with the exception of when there is no or lacking Data. 350 L or .475 L
I dont Hot Rod rounds anymore myself, so its a non issue. After killing many, many deer and hogs with handguns, I've figured out that all that raw horsepower I chased as a young man isn't needed.

With that said, I do like BIG caliber slugs at modest velocity. I pucked up the .357 blackhawk as its a little brother to my Big Boomers and affords good practice on the Cheap. With the saving in lead and the Cheap powder, I figure its good medicine. I am finishing off the first pound of powder tonight. I can say that I wouldnt be afraid to shoot a deer with the little lee 358-158-rf lee slug at 50ish yards in this combo. It wouldnt be my first choice as I dont care for tracking, but if its all I had, I believe it would work just fine.


I use several different powders that interchange with shotgun loadings. Longshot is one of my favorites for heavy loads in 12 gauge and 10 mil. 296 for the .410 and 44mag. HS-6 for the Linebaughs.
