BLACK POWDER
Yeeehaaaa....love the smell of BP in the mornings!!!
Doug, glad you are enjoying the 44-40...and with BP too!!!
Like others have already said, John shared with us in great detail his black powder journey. He found the Swiss was the better "quality" powder of those days as I did. He also tested OE of which I did not.
My batch of Swiss FFg weighed equal 40gr as it also measured 40gr by volume. I never did try Swiss FFFg. Since John was perfecting the BP loads with 44-40...I didnt test much and went right in to the smokeless powder testing.
What little bit of testing I did was mainly with revolvers to somewhat accompany John's rifle work.
John was a lover of the Marlin aspect of the 44-40 so he liked to stay with the name "44-40", Marlin, Remington etc. He used Remington cases when he could because they are thicker/stronger. One can compress more black powder in the Remington cases and not have to worry about the case "expanding" from the compression step and not chambering.
Using wads is a bit of a waste of time and energy. Only a few cartridges John dissected had any kind of wad in it.....so dump the wads. Yes, I know the 200gr "Magma" bullets have a small lube groove. The amount of lube does help accuracy but really only after a certain number of consecutive shots. Shooting a few at a time before "wiping" should be fine. If you want accuracy throught 30 to 40 consecutive shots....by all means switch bullets to one with a larger groove. The Original bullet and the Lyman 427098 bullets don't have large amounts of lube but certainly a little more than the Magma type design/s.
It can be somewhat of a long story so I will save it for John to explain in his Black Powder Journey story. I will post a link below.
Read his work, you won't be disappointed.
