That is interesting about the Swift. Used it on two buffalo in both 375 (300gr) and 416 (400gr) with good penetration. Also on Zebra, wildebeest, eland, kudu, with weight retention in the 90s. On the 9.3, our own Hatari loves his and has taken a lot of African head with it. On the other hand our departed member Greg Rodriguez said he'd never use it on Buffalo again.

A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
