thank you all for sharing. As I look back on the numerous posts, it sounds like the answer to my original question is NO, there isn't one particular bullet that's been consistently accurate in numerous rifles. Reason for my question is that my Alaskan son and I are considering doing a sheep hunt and I would like to take one of my old .270s, despite knowing that both my rifles and the cartridge is rather inferior to the many new rifles and cartridges. Despite that and having loaded for mine for quite a while, I'd like to do some more load development hoping to find something especially accurate ( as in 1/2-3/4 moa) and want to avoid spending lots of money experimenting. I realize that accuracy is contingent on rifle, loads and the shooter but still want to start with some proven combinations. thanks again.
