I don't remember that he discarded the 257, but do remember he took a270 to Africa. I believe he used a mid weight 6.5, but do remember that he was not a hot rodder. I don't think that he made many shots over 100yds. I also think his shots were at calm/unaware deer. As far as why some double lung shot deer run and some drop, I believe it has more to do with the individual animal itself. The younger, smaller, 'slighter' deer seem to drop, while the older, physically, more mature, especially bucks tend to run. I have killed my deer over the last 30yrs using mainly a 708, 7x57, and a 30-06 using mid weight cup and core and Partition, bullets at normal velocities. They perform the same. Some deer ran, some dropped. Maybe if I had used a 7 or 300 mag more would have dropped. I don't know. capt david
