If you want to see red lung soup try a 100 grain ballistic tip out of a 257 Weatherby
I've seen lung soup many times. Mostly from .243's and .22-250's with what most folks would consider "varmint bullets". You don't pull the lungs out of a deer shot with them, you pour the lungs out.. Even a .223 with a typical 55 gr. sp is pretty darn good at the "lung soup" gig if the range is kept fairly short, as was my old .222 with my woodchuck loads using the old 50 gr. Nosler solid base "expanders".
