·This post is only one part of my testing results,these are my notes, informal I know but I want to preface this by saying these are my personal results and my testing methodologies. I pay for this stuff out of my own pocket and I test it for my own benefit. I am not an "Expert" or a ballistician. I strongly recomend that you always test your own ammo/defensive pistol combination for your specific needs and only carry/depend on it when you are satisfied and confident.
Dane gives me the opportunity to share my writing/ideas here so I post them for the benefit of others:
Tactical Penetration and Cars (Sheet Metal).
On Saturday afternoon I had the opportunity while testing the new Black Hills 230gr Gold Dot ammunition to also test it against automobile sheet metal and I was very impressed.
I used three pieces of auto sheet metal (patch panels from the Eastwood company) spaced 3" apart mounted on 2x4 framing with two large semi boneless Hams behind them.
All shooting was done from 24” directly facing the target to realistically duplicate standing next to a vehichle door. I recognize that we are shooting at a flat surface and this may not be a complete representation for shooting at cars but: *I must explain that this was done as I did not want to have rounds go skidding off into my range area in odd directions. *I learned this the hard way once when a Corbon .45acp 200 gr. +P load literally skimmed along the metal surface and bounced off of the wall and went up-range after shooting at the metal panels at a 45 degree angle. I was not injured but… (Safety, safety, safety)
Ok, on to the Sheet metal results:
The really suprising aspect of the gold Dot bullet is the way it performs, specifically the large cavity of the BHGD cuts an almost perfect circle of sheet metal and the discs are then somehow "dropped" or dislodged by the gold Dot hollo point cavity as it continues into the target material and the BHGD expanded to .70" on average and penetrated to a depth of 11.3 inches into the Ham, (I need to note that without photos it may be hard to understand the distinction I am making here.
If I were primarily concerned with automobiles as tactical barriers I would strongly recommend the Gold Dot 230gr bullets)
Comparison:
I tested the BHGD side by side with my favorite loading the Winchester Ranger 230gr +P Talon round and the Talon load semi-clogged on all five test rounds with the "disc", then traveled into the target and still expanded to .73" on average across the semi extended Talons, it penetrated 9.4 inches into the Ham. In comparison the BHGD resembles the classic flat almost square nose profile fully expanded bullet and the WRT is the classic mushroom profile semi rounded shape bullet, the WRT did not expand completely and the Talons were only partially opened, with ham grisel caught in them.
As to velocities the WRT +P clocked 1,020 fps from my SS Springfield TRP.
The BHGD clocked 905fps from the same TRP; this is 5 fps higher than Black Hills advertises.
I am looking for a new service to post some more of my pictures; I hope to have them here shortly.
