Beyond shot placement and what it hits, penetration is a factor of:What do you mean? Moving too fast or don't expand enough?
I just like them because they look like flower petals!Beyond shot placement and what it hits, penetration is a factor of:
1. Mass x Velocity Squared (ME) the physical determinant of stopping distance
2. Sectional density
3. Bullet expansion, more expansion leads to lower actual sectional density
Bullet expansion in turn is a factor of:
1. Bullet construction
