[Blue Collar Christian]

A lead wadcutter, round nose, or a plated flat nose, etc. bullet would penetrate considerably more than an expanding hollow point. But maybe not through blue balloons. I’ll say 7.

In the 44 mag, the 265 gr jacketed flat points made for the 444 Marlin did not expand and penetrated many water jugs if it did not veer off. Probably would not penetrate blue jugs though!
