A deformed tip does effect the bullet but not as must as a deformed base.

As for penetration, load a round slower and it'll penetrate more. Load it hotter and it'll expand more. I've done Varmint grenade 36gr loaded to barely move the bolt of an AR and it penetrated deeper then a full load 55gr sp.

Great post. I guess for rifle rounds that makes sense. The extra velocity would put undue stress on the round causing it to tear apart.
