Ballistic Performance Evaluation – Part Two

In Blog by Rich0 Comments

So this is the follow up from last week’s article on evaluating the ballistic performance of projectiles. Specifically, we’ve been looking at the differences between the 105gr Berger Hybrids and the 115gr DTACs. In general, the heavier the bullet the better the performance. That isn’t always the case and just because one bullet is bigger doesn’t mean it will have better ballistic performance. If the bullet has a poor design it can just be bigger and heavier without necessarily having better ballistics. Why would you want that? Well, Hunters are concerned with good terminal ballistic performance at closer ranges a lot of times. Some guys hunt long range but even still the average is probably around 650 yards. If you aren’t shooting as far, you can afford to use a bullet that’s a little less slippery as far as ballistic performance. The tradeoff being it knocks down the animal you’re hunting. For the rest of us interested in competitive and recreational shooting at longer ranges, the BC numbers tend to be pretty important. In this case it’s a difference of almost a full tenth of a point. The Bergers are currently rated at around 0.53 and the DTACs are pulling 0.62. Last time we looked at some of the numbers on paper, this time…we’ll see how the DTACs did in the real world!
