I actually had never heard of a bore cut until I got on this site. I had always cut a "triangle" into the holding wood (with the apex pointing at the start of the backcut) and chased leaners. Gives you less wood to get through (and therefore a faster cut) where the risk of barberchairing is the greatest.
This tree was actually the first time i used a bore cut. The distance from the stump to where the second piece stuck itself into the ground gives a better idea of the lean than the perspective offers. I cut a big open face on that one.
This is called the "golden triangle" or "coo's bay" cut, very effective on heavy head leaners!
