BLUNDERBUSS FLINTLOCK BLACK POWDER BRASS BARREL PROOFING BROWN BESS MUSKET VS 6 GALLON JUG SLOW MOTION

1st proof testing of a 10 bore brass blunderbuss barrel using 180 grains of goex black powder FF and a .775 cal roundball with a patch into a 6 gallon jug of water. All mic'ed out perfectly with no stretching of the brass barrel. I will probably up it to 220gr with 2 balls another day.... .79 caliber Brown Bess's were proofed with 660 grains and 2 lead balls back in the day.. So 180 gr. with 1 ball is not that krazy...
