Win #540 Powder...???

Just made an inventory of the odds and ends of powder I've wound up with over the years, with intent to use 'em up, as I've standardized on #231 for all pistol from 9-mm MAK through .45 Colt, and #4895 for all rifle from .223 Rem through 8-mm Mauser. Found an unopened can of Win #540, which I can't locate mentioned in my manuals for anything I reload for, so it must be pretty old!:scrutiny:

What can I use this for? Can you direct me to loading data? Is there a modern equivalent I can refer to for data?:confused:

I happen to have a can of the same thing that was given to me many moons ago. I did a little research and found out it's exactly the same as Hodgdon HS-6. I don't recall the company that made the powder (Olin maybe?) but it was sold by WW as 540 and Hodgdon as HS-6.

The Speer #12 lists loads for 40 S&W, 10mm Auto, and 41 AE using 540. A couple manuals noted that it's at least very similar to HS-6, but that loads an velocities cited in the Speer #12 are just a tad different, so I'm not 100% sure they're exactly identical. Could be just lot differences. I've used a little bit as a shotgun powder -- mid-range field loads.

I have likewise heard that Win 540 and Hodgdon HS6 are the same powder. Win 540 is my powder of choice for loading 1 oz shot charges in my 20 gauge Citori.

Good shooting and be safe.

It was made by the St. Marks Powder Company, in St. Marks, FL. The plant used to be owned by Olin, but has since sold. Data for HS-6 and Winchester 540 are generally interchangeable, according to Hodgdon. Here is the quote from their website:

HS-6 HS-6 is a fine spherical propellant that has wide application in pistol and shotshell. In pistol, 9mm, 38 Super, 40 S&W and 10mm Auto are some of the cartridges where HS-6 provides top performance. In shotshell HS-6 yields excellent heavy field loadings in 10 ga., 12 ga., 20 ga., and even the efficient and effective 28 ga. HS-6 is truly an outstanding spherical propellant. HS-6 is identical to Winchester's discontinued 540. Available in 1 lb. & 8 lb. containers.


Hope this helps.

Old Thread- Loading some 38 specials with 158gr cast today. Hodgdon Maximum listed for HS-6 is 6.3gr. The Winchester Maximum for WW 540 is 7.1gr. Starting load 6.3gr This from old printed data. Edit Shoots like the same powder.

The Lee manual has thousands of pistol loads for W540.

They could still be the same powder. I seriously doubt WW and Hodgdon tested with identical setups. Now if someone like Hornady or Lyman tested the 2 side by side, in the same test rig, with the same components, and got very different results, you could argue they are different, and it would be very hard to dispute.

IMHO, this just reinforces the argument for comparing similar loads in several different manuals.

BTW, I do not recall where I came across the info I posted about years ago, but I found several sources, and searched until I found some actual published information. That much I do remember.

I used quite a bit in .45ACP loads in the late '80s. Not as good as 452AA, but worked well.

I've found the new data for HS-6 is a lot "lighter" than the older data for W540 but it's always been that way. W231 data always produced more velocity than the data for HP-38 and they are both the same powder too.

I've shot a lot of it in 12 gauge # 5 shot ounce-and-a-half loads. Lethal on Pheasant.

Hs-6/WW540 are my "go to" powders for "+P" .45 ACP, warm .45 Colt, 9mm.
You'll find that loaded in "standard pressure" (.38 Special as example) cartridges there is a LOT of fouling/unburned powder (?) that tends to tie up a revolver cylinder.

Loaded 6.3gr of both powders in 38 special over my 158gr cast. They shoot the same, most go into 3" @ 50yards. Same powder, different data.
