Brass is pretty hard on rifling, unless it uses sabots; but it penetrates well. I have considered machining copper shells, and dipping them into lead alloy with flux. Then a simple press sizing, and you've got a Nasty tip! 🎯💥👍🎯

Many new things to try, LOL!🚀🚀

Next time I see a herd of Tyrannosaurus Rexes charging, I'll call you (after I drop one); to come play! 🦖🦖🦖🦖
