Well I finally got my junk together and got to go spend my range time with the Fusil De Chasse. After a little tinkering, i'm well impressed with the accuracy. I'm having a fair amount of flash-in-the-pan-no-booms, I'm going to have to do a little investigating at the vent liner. It's already 1/16" but no idea about what the inside looks like. It's gonna put up a fight getting it out looks like.
I started with .600" ball, 90gr of FFG, with a .010" patch lubed with my new favorite "secret lube". Accuracy was basketball sized at 50 yards. Had a lot of flash-in-the-pan-no-boom, and the bore was really crusty in short order.
Dropped to 80gr, bout the same just lower POI. Upped it to 110gr and it tightened up a fuzz but not much.
Went to an .018" cargo shorts patch and the groups looked like groups! Showing promise!
Getting really burnt out on the ignition problems, I scrubbed the bore out and swapped to FFFG powder for the main charge and the pan prime. My dad's Lyman Deerstalker .50 is dead nuts reliable with this combo, figured it couldn't hurt.
Started at 70gr FFFG, .018" cargo shorts patch, "new secret lube", and sat the target right on the base of the front sight. Rattled off 5 shots without swabbing or anything and here's what I got:
That'll work! We're done here! I was scared to take that 6th shot, LOL. I wiped the bore and shot another about the same size and only had two flash-no-boom. I'll sort that out and we will be all set.
Here are my patches:
They look good to me, but I'd be all ears to yall's thoughts. And yeah, brown is a TERRIBLE color for a patch, but these were my old pair of shorts and I don't wear white or yellow
Oh yeah, about that "secret lube".. It really seems to keep the bore free of crud, and what is there wipes out easy. Also cleaned up fine with water with a drop of soap when I got home. I was using ghee, which is solidified clarified butter, and it made a crusty mess in the bore. This stuff does none of that. Only negative: the patch is covered in ants by the time it hits the ground
For you curious types, here it is:
I dunno what's in it other than some sort of beeswax mixture. Works awesome on leather, and it smells like honey. All natural, Won't kill ya if you eat it or get it in your eyes according to the MSDS.
Thanks for following along and helping me out with this old gun. I sincerely appreciate it!
