My Encore in 460 S&W Magnum with it's 15 inch braked barrel will send bullets down range faster than any revolver. Besides my take of the Zebra, the 250 gr. SST/ML bullets took down a Red Hartebeest, an Impala, a European Fallow Deer, an Impala, a Duiker, two Cape Grysboks, a Vaal Rhebok, Khalahari Springbok and a Steenbok.
I've also hunted with a 357 Herrett using Hornady 158 gr. XTP bullets. That gun took a Springbok, a Mountain Reedbuck and a Black Wildebeest.
A question on your experience with your Hornady XTP bullets blowing up. Did the deer die and if so how far did it go?
