I even use Nitro FOR Black loading techniques to load lead bullets and lighter than normal jacketed bullets in my 450 No2. They are fun to shoot [almost no recoil] and have power equal to modern 45/70 loads. Fine for deer and pigs.
400 grain cast at 1822 fps.
405 grain jacketed at 1800 fps
300 grain jacketed at 1878 fps.
These loads shoot and regulate with the sights to 50 yards.
Because they are slower than the full power loads they have more drop at 100.
