The shape of a hp plays a huge roll in how a bullet performs. Same bullet with different hp shapes/depths.


The penta point hp is good for 800fps to 1000fps
The large round hp is good for 1000fps to 1200fps
The small round hp is good for 1200fps to 1400fps

Some different hp's for the 38spl's/357's. Just looking at them it's easy to pick out which bullets to use for low velocities and for high velocities.


The large hp's are from a custom mihec mold and are excellent in snub nosed revolvers (top row 2nd from left).
The cramer bullet (bottom row center) is a #25 from the 40's. It's called their "hunter" bullet and was designed for hot loads in the 357mag.

For slow moving bullets you want a large/wide hp with good depth. A slow moving bullet ='s under 1000fps.
