It's comforting to know the Ruger #1S can handle the stoutest of loads...
But it's also a heck of a lot of fun to make pretty darned accurate blackpowder .45-70 loads, using 55gr of FFg, 5gr of WW231, Wonder Wads, swaged Marcel® bullets, and Crisco as the bullet lube. Smells like a Chinese takeout kitchen each time a round is fired, and you can actually hear the round as it impacts the berm at 100 yards. There's that beautiful cloud of smoke, wafting back towards the munchkin in the picture above, too. The BP loads are so comfortable to shoot, she's not intimidated by them, unlike my Beartooth 405gr/Reloder 7 2100fps zingers. (Which intimidate even my 6" 200lb carcass)
