[QUOTE="Allen, post: 160128, member: 389"] At this point I have still shot a LOT more critters with lead than I have with copper. The copper bullets do indeed hold together vastly better than any lead bullet I have ever used. In particular, some of the more accurate lead rounds for my 25-06 and 7 mm were the Winchester BST's and some of the accubond offerings. However, while they were great at distance (in both accuracy and performance), at close range the lead rounds really came apart because of the speed. This hasn't been an issue with the copper, I've only recovered a handful of copper rounds from formerly live targets because they more often go all of the way through and end up in the ground somewhere down range. In that sense, one simple point in physics will tell us that the lead has better "knockdown" power over a similarly sized/velocity copper bullet. When using F = MA in ballistics, the force of the impact is equal to the mass of the bullet times the acceleration. Or rather, in this case the deceleration of a bullet. When the bullet comes to a complete stop in the animal, F is greater because the acceleration is greater. Any bullet that keeps on traveling through the animal is still carrying part of its original energy down range until it hits the ground. So one needs to weigh the different advantages between them. On the one hand, the copper staying together provides quite the wound channel through the animal. On the other hand, lead more often will impart its full energy into the animal producing impact shock damage farther away from the point of impact. If you are a good shot, go for copper. If you spray and pray, stick with lead. [/QUOTE]
