My 300 Ultralight shoots very well.
Weatherby did have to repair my trigger as it a lot of take up. They also changed out the stock do to some unfilled areas, they replaced it with a different color scheme. There customer service was great. Asked them to range certify while it was there, they did that to. 180 Barnes TTSX .52 and .72 . I cant hold that tight but under a inch at 100. I put a Leupold VX6 3-18 on it in A Near manufacturing 1 piece base. And before that scope went haywire it grouped consistently under a inch with 180 Nosler BT and a charge of IMR 7828 @ 3150
With max charge according to Nosler manual speed was 3250+. So the barrel seems fast.
I like em. Get it๐Ÿ˜
