just last week.

firing .577 Sniders, 577/450 Martini-Henry, a .450x3 1/4" side by side rifle, and a 500x3" side by side rifle. All loaded up with plenty of black powder! what fun! I love shooting big old SxS rifles and BP singles!

Still working out a few things with my 577/450, I have all the gear I need now and am just working on finding the best loads. It has lots of potential.

Attached picture features the 577 Snider and 577/450 MH with a 45-70 in the middle.

I'll try to get a pick of the big 450 and 500 Express cartridges compared to some others to.

here we go.
