Erimicus's experience is consistent with a friend of mine who used the 150Gr. Bronze Point for years. He had a pretty good percentage of shot & drop deer, but every now and then one just seemed to run off. A couple that did drop didn't have deep penetration. That experience plus my own with Ballistic tips, leads me to beleive, if anything, the Bronze points (at least in 150Gr.) penetrated even less than the Ballistic Tips.
My direct experience is with 180Gr. Bronze Points. In an older Ruger #1. They will give me 1/2" groups all day, but I've never shot them at game.
