Im not sure what to think of this. Good? 65.5gr nsa 1015fps shot into (thru) a gallon of water into towels at 125 yards. Impact speed in the area of 875fps give or take. 
Opinion on this slug expansion
- Thread starter vmaxpro
- Start date
I would try and use an exacto and cut slits so it may open up like flower petals.

i read an actual investigation and study done by the Alphabet org after a couple of nutjobs shot up and killed several officers in florida several years ago ...the officers 'pistols' proved to be inadequate and they wanted to find a 'better' pistol round option, and it just so happens that airgun velocities are in that same ballpark .. what was concluded in summary is that expansion means next to nothing and only base size of round and penetration were the key ingredients to incapacitating something ... in the end they developed the 10mm auto to be the most effective pistol ever produced ... then of course it got watered down so pansies could handle the recoil and we got the .40 ... but anyway yeah .. i wouldnt worry about expansion ... hitting your target and shot placement is about all we need to worry about with airguns with the added factor of deeper penetration at a distance with a heavier round ... this of course sacrifices point blank zero range ... so in pre-planned scenarios like hitting a deer size animal at 50 and knocking it out a heavier projectile sighted from your stand to an expected spot would be ideal ... the expansion thing though .. not a factor in the real world ..

Vmaxpro, it depends on what it hit. I would consider that minimum or a fail. It definitely would cause shock to the target, but the damage would be based on velocity, not expansion.
Hollow points need liquid to initiate hydraulic pressure for expansion

This is cross cut 78gr 257cal HP bullet shot at gallon waterjug 1100fps. It surely works and most cases you get full fragmention after it opens this wide.
