230g Gold Dot Captured
#21
My guess is that if one Speer bullet is "less tough" than another, it is more due to the shape of the bullet rather than whether it is a GD or DC. That 45cal/230g GD bullet looks like it has a pretty deep hollow point, unlike the 45cal/300g DC. The DC 45cal/250g (Long Colt) is another bullet that does not hold together well in torture tests and it also has a very deep hollow point.
Every other bullet across a wide spectrum held together, some did much better than others in expansion, weight retention, and penetration. The 240 as you can see was very impressive. The pictures don't really do it justice, its literally turned inside out and basically held completely together.
