well that was a lame result i thought it would open up a lot more and stop in the 3rd jug? subsonic 9mm rounds are less expansion then i thought
i bet the lead is softer then the basic plated one i used and a real hollow point they have cuts in the brass to help it fold back and the brass acts as a wall to control the expansionThe 147 gr hst is designed to expand at subsonic levels. Perhaps the bullet you shot that you drilled out isn’t suppose to expand at all. Ammo manufacturers have a special mixture they use in bullet making that helps them to expand/not expand so they control what they want the projectile to do.
yeap went at least a quarter inch into the bullet also good size hole, i have shot them into wet phone books and they broke up in pieces? must be harder lead content in themWas that hard ball that you drilled out?
The entrance and exit of the 3rd jug holes were 9mm size when I look at in closlyLead in plated bullets I’d usually pretty soft.
How did you determine there’s was no expansion when the bullet wasn’t recovered?
With jacketed hollow point bullets I think the jacket composition, size of HP, the perforations in the jacket all determine when and how much the bullet expands. Drilling into a plated bullet is a neat experiment, but doesn’t replicate factory ammo.
this new one to the left is about 132 grain after sanding a lot of the brass jacket down it was thicker then i thought and i trim down the bullet nose some another test comming soonInteresting experiment, but I wonder what the bullet actually weighed since you drilled out part of the heavy (copper and lead) material and replaced it with a lighter material (silicone). I'm sure it didn't weigh the original 147 grains.
