Out of a Marlin 1894, the bullets shoot into the front sight (a 6-moa dot) with boring regularity, and they hit the steel plate hard enough to foul it on it's chains, necessitating going downrange to unwind the target from it's stand.That bullet is a custom, 180 grain, tumble-lube, gas-checked, wide flat nose bullet that a bunch of us designed on the Cast Boolits forum several years ago. It was designed for the .35 Remington cartridge, but several of us stuffed it into a .357 magnum case with a stiff dose of L'il Gun powder. And something magical happened.
That bullet runs out of the Marlin at something over 1600 fps and that wide flat meplat hits like the hammer of Thor. You'll note that the boy said they'd have to walk downrange to un-foul the target from its stand. I know that particular range, and it's about 80 yards from the firing line to the gong.
It's a great load, out of a light, handy, short carbine that gives sufficient energy out to 100 yards for whitetail deer and hogs. The .357 magnum and the lever carbine are a great woods-cruising combination.
