I to am interested in the 7mm saum. I shoot 140, 145 and 150grain from my 7mm Weatherby but it doesn’t stabilize heavier bullet well. does anyone have experience with the older Weatherby barrels and if so have they been able to find any bullets above 150 grain to shoot well. Another question does the seven saum shoot a heavier bullet well or is it a better lite bullet or target caliber?
It's the stupid 1:10" twist that Wby put on them that is the problem. I have a MkV 7mm Wby. It shoots 160gr Barnes well, but I shot a bunch of Federal-loaded 160gr copper tipped bullets out of it, and, at 100 yds, they all were making oval holes in the target.
