Thread: .270 140 game kings exploding

Just a comment about the GameKing vs the Pro-Hunter.

When it comes to the construction they are made on the same machines using the same materials and the same process. I have an interesting email thread with one of the Sierra technicians who I talked to regarding exactly this issue. His comments about relative toughness:

This is a fantastic question and you are correct [that there is no tangible difference between their performance on game]. When it comes to the same weight and same diameter, like your #1560 and #1540, the two bullets are made the same way with the same components. This means we use the same style of jacket surrounding the same style of lead core and the process putting them together is the same. The only real difference is the shape of the bullet and by adding a boat tail to the rear of the GameKing, it gains BC numbers. Because it is more efficient in flight, it doesn’t slow down quite as much through the same atmosphere and will therefore hit a target at the same distance a little faster. At the range you are taking animals, the bullets are still going a similar velocity on impact so I’m not surprised you’re seeing similar results. Every now and again, I’ll get reports that our GameKings are more fragile than our Pro-Hunters (with all other things theoretically equal) and my theory for a reason is because there is less bearing surface on a GameKing. This gives the lead core less friction to lock into the jacket with, giving the impression it expanded quicker in relatively similar hunting situations.
