Following are photos of 230g 45 caliber Gold Dot bullets. Speer calls this Gold Dot bullet, a bullet for 'personal defense'. The recovered bullet on the left was fired from a 45 acp pistol. The recovered bullet on the right was fired from an Omega rifle, pushed by 80g Blackhorn powder.
The bullet on the left weighs 230g. The unfired bullet weighs 230g. The bullet on the right weighs 93g. The water jug in which the 93g bullet was found has little holes in it's back side from pieces of lead thrown from the bullet.
The velocity of the bullet fired from the 45 acp, was about 900 fps when it impacted the 'trap'. The bullet from the rifle impacted the 'trap', traveling at about 1550 fps.
This is not a Deep Curl bullet. This bullet doesn't seem to be as stout as a Deep Curl bullet.
The following photo shows a 300g Deep Curl bullet captured at varying ranges by jugs filled with water, and phone books.
At 45 feet the bullet was traveling at about 1800 fps; it weighs 276g. At 200 yard, the bullet was traveling at about 1300 fps, and weighs 300g. At 300 yard the bullet was traveling at about 1150 fps, and probably weighs 300g.
The Gold Dot doesn't seem able to handle these speeds, whereas the Deep Curl seems to work good.
Speer names the Deep Curl a 'hunting bullet'. Speer calls the Gold Dot a 'personal defense bullet'. It seems that is how they were built.
