Well, they worked quite well on game as well as paper.
I dropped two pigs (one a finishing shot) and an axis doe with one shot each. Both pigs were DRT, while the axis ran about 40 yards after a DC through the heart/lungs. Recovered one bullet - it was a prime example of lead expansion. After breaking a shoulder and plowing through most of the pig's neck bones, it was resting peacefully against the off-side hide. It was about the size of a half-dollar and relatively flat after a hard impact at about 35 yards. The other pig had no exit wound, but my brother (who skinned it) did not find (or didn't look for) the bullet. At 130 yards or so, the 260 grain DC broke the axis' shoulder, took out the top of the heart and both lungs, and exited through the middle of the ribs.
Overall, I'm extremely pleased with this load in general and the DC bullets in particular. I can't wait to try them on elk in December (fingers crossed hoping I draw a tag).
