I remember when Winchester made the decision to discontinue the Black Talon line because of political pressure by people who vilified the round and made it sound like the deadliest bullet ever invented. People like Democrat Patrick Moynihan who described it as a buzz saw ripping through you on TV. So Winchester decided the best course of action was to stop making it. Of course, they really didn’t stop making them, they just removed the black coating and renamed it. But before they were all gone I went to my favorite gun store, The White Elephant, to by a box.
The only caliber left was some 10MM. I didn’t own a 10MM and didn’t really have any desire to get one. Not that it really mattered, I just thought it would be cool to have some. Years later, last year, I picked up a used Colt Delta Elite.
The first round in bare gel had a velocity of 897fps it penetrated to 17 inches and expanded to .82 inches. Round two hit at 912fps with 16.25 inches of penetration and expanded to .84 inches.
In heavy clothing, the first round had a velocity of 944fps and penetrated to 16.5 inches. The expansion was uneven with only one side of the bullet extending outward to .70 inches. Round two went into the block at 992fps and penetrated to 17.75 inches. Like the first round, expansion was uneven at .65 inches.
