You may check out Weatherby .220 Rocket (.220 Swift Improved) if you are going to re-barrel your 77V. I had mine rechambered in 1979 by Huntington's and it has made a world of difference. It does not stretch brass any longer and gains a couple hundred FPS. It will fire standard 220 SW and is a dream to load for. Mine shoots a Sierra 52/53gr HPBT Match at 4K FPS with pressure to spare, and 5 holes touching. It has killed dozens of prairie goats and mulies up to 500 yards and hundreds of rats . My only regret is not re-barreling with a 1/9 twist to shoot the Sierra 69gr HPBT Match.
