Hey everyone, I've got a custom .260 that I built up on a Rem 700, that with 123 and 142gn SMK's will group 1/2 moa consistently. My question is, what is the realistic max hunting range of this calibre?, when used on deer sized game? The numbers I have run tel me that the 142's hold 1000ftlbs out to around 600yds. With sufficient accuracy to group inside 6" (vital zone)at this range, I summise that 600yds would be the max for this cartridge. Am I assuming correctly?
