Customer Product Review- G. Wallace September 8, 2016:
I followed your advice to "stay safe and aim small" with the result you see in the attached photograph. Rifle was my Browning BLR in .450 Marlin fitted with Skinner rear sight. The bullet was cast from plain wheel weights, air cooled, and weighed 406-408 grains from your 457-405-F mould and lubed with SPG. At 1800 fps it passed through both shoulders of that big Buff at a range of 110 yards and ended up an inch under the skin on the far side. One shot kill, so I never needed to find out whether the water-dropped bullets would have made any difference. Difficult to see how performance could possibly be improved. Thanks to you all.
