The Hammer Bullets (in stock) arrived 6 days after the initial internet order. They are precision bullets. Here is the free bumper sticker in the package:
The hollow point opening is 0.250" diameter at meplat of about 0.300" diameter, and the hole tapers to a point in an ogival way, about 0.400" deep at most. Should be a "Shock Hammer" when it lands and slick traveling inside a barrel. There are 6 grooves, streamlined in both directions, 0.458" major diameter, 0.450" minor diameter. Crimped in 4th groove: 3.340" COL, 0.490" seating depth Crimped in 5th groove: 3.450" COL, 0.380" seating depth Boat tail is about 0.250" long, reducing from .458" max to 0.400" minimum diameter. That is about 87% of caliber at the base. Probably would be too blunt to feed from a magazine box if tried in reverse for a solid. Still wishing for an aluminum or plastic ballistic tip to press-fit into the hollowpoint. Maybe just a 0.25"-diameter plastic sphere to act as a feed cap on the HP end ?
