I want to test verious bullets to see how they might penetrate/ expand on hogs. Anybody have any ideas on how to make a somewhat realistic target to test on? I don't mean real looking, I mean how to simulate shield, shoulder,bone vitals,bone, meat, sheild. i've got lumber, cardboard, 5 gallon buckets, and variuos othermaterials and also a nice dirt pile to shoot into and recover bullets. any suggestions?
