Nice looking rig!!! I would love to use that rig in the woods, but can't in Virginia. Can't use it for hunting deer.
But that load would test anyone for sure. I shoot my cap and ball pistols, but with nothing close to that load and bullet weight. I would love to try working with one. I have two contender frames with ten barrels and about five hunting rigged hand cannons.
I would love to hear what the chronoed velocities are for the different loads. Please get back with us and let us know the data.
