I knew that Wano and Shuetzen powders were made by the same manufacturer. I didn't know that they were using Alder charcoal. Thank you for the citation, Pete.
Their burn rates do not equal the Swiss powders, however. And, I suspect there is a difference within Alder Charcoals, depending on when the bushes are cut, and where, and how long they are allowed to dry before they are heated to charcoal. There are two other things that Swiss does to its powder making- besides using Alder charcoal, that can affect velocities. They use a slightly higher proportion of Potassium nitrate; AND the size of the granules is smaller than the comparably designated American Powder sizes.
Since Powder burns from the outside inward, smaller granule sizing puts more granules of powder in the same space, and that will produce more gas, faster, when burned.
When my brother tested his Swiss powder vs. his Goex 3Fg powder in his .40 caliber rifle, he found that equal amounts, by volume of the two powders produces a couple of hundred FPS more velocity using the Swiss powder.
However, when he used a Walter's Vegetable Over powder wad on top of both powders, using the same volume measure of powder, and the same PRB, a greater improvement was seen in the Goex powder, than in the Swiss, and the Gap between the two MVs closed to less than 100 fps.
I would expect to see the same result if Wano, or Shuetzen, or Graf, or Kik, or any other brand of Black Powder if a similar test was done to compare velocities with Swiss powders.
On cleaning the barrel after shooting both powders with the OP wads, BTW, Peter found that both barrels had the same amount of residue on his patches, and both were as easy to clean as the other. That would seem to indicate that giving Goex a Better Seal helps get more complete burning of the powder, for maximum performance. Oh- SDV dropped for both powders, using the OP wads, too. The Greater drop occurred with the Goex powder.
I did not call you wrong. I merely thought you made a mistaken assumption. I WAS WRONG. Thank you for correcting me. :surrender: :hmm: :thumbsup:
