I picked up some Ranger 127+P+ to try. The performance of this through auto glass (from Winchester's data) is 58% weight retention, 9" penetration. In fact most of the non-bonded versions do not do too well. Aren't bonded bullets a smarter choice these days? Do non-bonded bullets offer any advantage in non-barrier shootings? From all the data I've seen bonded ones tend to give just a little more penetration in almost all tests, and superior weight retention (sometimes drastically superior) in barrier tests. What would you say the break down in % is of agencies using bonded vs non-bonded?
