  1. This is definitely one of ... review by Ralph on 6/12/2017

    This is definitely one of the best molds for lever action rifles. The bullet actually casts 415 grains with 30-1 alloy. It does have the very necessary flat nose for use in lever rifle magazines, yet is more streamlined than many other choices.In my \'86 Winchester I load 63 gr GOEX Cartridge black powder, compressed under a Walters .030 wad, to the maximum cartridge OAL of 2.550 inches. Velocity in my 22 inch barrel is 1150 fps.You could probably obtain 1400 to 1500 fps using smokeless powder using this alloy bullet. Above that, barrel leading will likely occur.

    Great mold! Drops them at .459 with 20:1 alloy. Lyman and Ochocos are the best!

  3. Good Mold review by Critter on 6/12/2017

    I purchased this mold to cast bullets for my 45-70 encore. The mold is typical of any other Lyman Mold I own or have used . The one drawback was that the pins and holes do not line up properly so when the mold got hot it did not want to close. I was able to slightly modify the pin to eliminate this fault. I fell this is a needless annoyance for the price paid.
    Within 10 or so attempts, the mold began dropping well formed bullets with few rejects. This was with a 50% wheel weights and 50% pure lead alloy. The bullets filled out nicely, dropped at 427 grains and were .461\" in diameter. I resized these to .459\" for my barrel. Pushed by 25 grains of 2400 and a Dacron filler I obtained 1400 fps. Accuracy was stellar averaging 5 shot groups of 1.03\" at 100 yards.
