I'll have to do that next time I have a lead pot fired up. I was curious because Ballistic tips and Accubonds aren't really a cup and core. The 120 gr 7mm Ballistic tip is a weird one; it's 3/4s jacket. The Woodleigh is an easy opening bullet that sheds about as much weight as a Partition. Fast killer.
Interesting. Although I did notice the 130bt is basically the same length as the 150 partition in 277cal, so having a lot of lighter jacket material would help account for that.
I think that's why he added the smiley at the bottom. Also the federal trophy bonded tip.
Or the swift a-frame... Lots of good bullets these days...
