Elmer blew up quite a few handguns doing just that! He was well known for reducing.44 Spl. to small parts.That's why the author ended the article, "But I finish as I started: duplex and triplex loading techniques though fascinating are potentially dangerous and I would not recommend anyone to go there: CAVEAT EMPTOR!"
I am sure he did, and perhaps part of his experiment - risks taker.Elmer blew up quite a few handguns doing just that! He was well known for reducing.44 Spl. to small parts.
Yes. Many years back, we tried this with a few handgun and rifle loads, but or results were mixed at best. We had better results in some handgun loads, but eventually, we went away from the practice. Especially in rifle and with the more modern powders.Trade secrets! IIRC, Elmer Keith did some duplex/triplex (2-3 different powders - stacking them, not blending). I am pretty sure there are other hobbyists that does it too.

This is fairly common. Most ammo manufactures develop loads based on the latest lot of powder produced for certain calibers/loads, and with pressure gauges, indoor ranges, etc, etc, they create a workable load to sell to the public. These powders are usually considered non-canister grade, as they may not meet the tight specifics to be labeled as a certain powder, say like H4350, H1000 or any such.I have heard that there is some ammo, Hornady 204 Ruger for example comes to mind,
that "You will not improve upon" performancewise. This is supposedly because they
are using some powder that is not available to the hobbyist.
?????
What could they be using ? Where are they getting it ?
I think I've heard such about Weatherby too.
There's only so much pressure you can put into the chamber before you make a bomb, and an overbore cartridge certified at high pressure is hard to beat. 204 Ruger is already specified 2500psi higher than the parent case (222 Rem Mag) and hits 4400 FPS out of the box. Only marginal gains to be made there unless you push pressure hard.I have heard that there is some ammo, Hornady 204 Ruger for example comes to mind,
