Or, just cast your rifle bullets out of 10-13bhn alloy (unquenched/unhardened clip on wheel weights), select a wide flat nose (or hollowpoint, but trust me the wide solid meplat works), load them to 1600-2000 fps, and go forth and kill things. There is no need to over complicate this stuff!! (Fun as it may be to do that very thing.) Those simple principles have been working for hunters since before our great grandfathers were born.
