O'Connor pretty much setteled on 62gr of H4831 and 130 Nosler in his favorite M70 Winchesters at the end. He said he had a custom mauser that would give the same velocity at 60 gr of H4831. Very early on he liked the Winchester 130 Pointed Expanding and then for a while the 130 Silvertip. Some others were mixed in, but this is what he mentions most in 130 weight. Hornady is the only place that shows 62 gr of H4831 these days.
