I had a chance to shoot a couple rounds into wet phone books. I picked up a used 4 cavity hollow point mold from a member here and cast some boolits to a SAECO 5. Coated with HF red, I sized them to .454 but there isn't much sizing going on and could probably just seat them right out of the oven. The barrel in the Glock 30 looks lead free so far. Shooting 5.0 Titegroup and not sure about velocity.
The one in the middle got hit by another boolit and the left one went the farthest in the wet media.
