I took a dremel and cut a 180 hybrid and a Vld in half. I saw were someone else had done this. I however got different results than the other guy. The two that i cut in half looked the same. The lead came just as far in both bullets. The void between the lead and tip of bullet looked identical. I then did the staple method that was talked about to test hollow points. I put staple in about 15 of each bullet. The depth the staple went in was the same. Best i could tell. The hollow point is larger on hybrid. But thats only difference i seen. Jacket thickness looked the same also. But with cutting tool smearing jacket, i didnt really worry about that. How much thicker is the jackets on the hybrids over the vlds?
