I'd like to use W-540, and welcome any comments pertaining...
I debated where to post this, and chose this forum, since my question is 1911(clone) specific.
Yesterday, I put money down, on a new RIA (Rock Island) 1911 in 38 super. I hope to have it in my hands within 2 weeks. My end goal, is to work up to full power loads (+p) with a 128 TC/SWC boolit (My NOE 128gr SWC is shaped much more like a TC than a SWC, so I tend to call it a TC.
I've been reading some old threads and I was glad to see this, from (10-17-2012).
I have a couple lbs of W-540, one in plastic jug and one in old steel can, I'd like to use up this old discontinued powder.
I read from many sources that Hodgdon basically "rebranded" W-540 and calls it "HS-6"
This is good, as I can't find 38 super data for 540, but I can find HS-6 data from many sources.
Also a old post from ReloaderFred on this topic:
From Hodgdon website:It [540] 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.
https://www.hodgdon.com/hs-6/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.
