(This video was first posted to YouTube on June 2, 2017.)

Shooting the 44 Magnum cast with the large round hollow point, 1:40 alloy with a BHN of 8.0 into Clear Ballistics Gel from my S&W 629 with a 3″ barrel. This series is a long experiment testing powder coated cast lead hollow point bullets made from various alloys and fired at various velocities.

Why is it when we test things it seems like we sometimes find more questions then answers?🤔 the bright side…… more testing!👍😁

I’m guessing that the missing PC on the drive bands is because the soft lead was scrapped off in the forcing cone because the soft lead tried to obturate in the cone rather than size?
Is this a good example of exceeding the working pressure of the lead? Do the bases of the recovered casts show some concave rather than flat?

At least the 2 rounds that you recovered expanded… somewhat. And they weren’t complete pass-through.
You may get similar results with your rifle, as you experienced with the 29. The BHN being 8, you may experience the same leading of your barrel on your rifle, too?
