Home Made Black Powder Vs Swiss Speed test (chrono)

OK....this has been rather difficult....I wanted to make sure I was loading as accurate a load as I could so the test would be fair and I have never thought you could get exact measure from using a flask and spout I weighed the powder with a digi scale...(which turned out to be far from accurate) with the first go round...which I decide 25 grains by weight would be a good load for the test...well it was for my powder and swiss but 25 grains of goex would not fit in the dang cylinder of the .36....crappo...so the next day I tried again...this time using a Lee grain scale and dropped it back to 15 grains so there would be room for the goex this time....well it worked but it didnt...the 15 grains fit just fine but the ball did not really get as good of compression with my powder and the Swiss as it did with the Goex which is a bit larger in size....soooo as it turned out the Goex (with more compression) was actually faster....geez what a pain!...so anyway the speeds I got with mine and the Swiss I believe to be pretty accurate since they had the same compression...the Goex being bigger had an unfair advantage...that being said...check out the video..
