I love bullets with high BCs. I hunt varmints and "varmint bullets" usually have low BCs. I have a friend who made some 52 gr varmint bullets using J4 jackets(very open meplat...1/32"). I shot them in my modified 222 and get 3500+ fps. They dropped significately at 200 yards, so i decided to insert a plastic ballistic tip in them and their drop was reduced by half and their terminal performance in ballistic gel was identical to open meplats A calculated BC was nice, so I made a ballistic table based on this BC. These tipped bullets would not stabilize in a 14 twist, modified 222 so I had a 12 twist barrel chambered. Today a small ghog exited a barn and proceeded to eat...230 yards. My table called for 8 clicks elevation, so I complied. New barrel, new bullet, untried ballistic table...dot on chest and I sent one. The bullet hit the dot and the ghog just dropped/stopped/nothing...very dead. No blood anywhere? I found the entry wound and with a little compression, a small exit wound was noted. Ghog was a not pregnant/nursing female which is very unusual this time of year...she really wasn't that ugly.
