(This video was first posted to YouTube on September 1, 2017.)

Shooting the 44 Magnum cast with the large round hollow point, 1:25 alloy with a BHN of 8.7 into Clear Ballistics Gel from my S&W 29 with a 6.5″ barrel. This series is a long experiment testing powder coated cast lead hollow point bullets made from various alloys and fired at various velocities.

I forgot to say that my intention is to push these bullets at 25000 to 30000 psi or near max pressure

I have started casting 124 9MM HP. I have cast them at 2% tin & 2% Antimony and now I need to decided on heat treatment because I powder coat. Can you tell me if these bullets were fired using gas checks and what was the pressure developed. I am trying to determine if this BHN of 8+ can with stand higher pressures without gas checks without tearing apart on the way to the target. You can reach me directly at rholt@richard-holt.com if you do not want to discuss these questions in an open format

8.7 hardness is good to 11K of pressure, which is slow. the 10 gr of unique looks to almost double that pressure but shot great. Love this testing

A man’s gotta know his limitations…. LOL
I would agree with your assessment, half way between your previous test and this one should be about right.

I’d have no issues using this load as a woods protection load (2 and 4 legged) animals. I always thought that some fragmenting is good because it opens up other wound channels. For hunting I’d prefer a solid SWC.
