The Bergara B-14 series of rifles offers several chambered in 22-250 with a 1:9 twist.
The Ruger American Rifle was offered in the 22-250 chambering with a 1:10 twist.
I'm looking hard at the Bergara. The 22-250 will outrun the 224Valkyrie. But the 22-250 would be useless to me without at least 24 inches of bbl . . . 26 would be better.
Would you have enough mag length for a 80 or 90gr bullet loaded into a 788 mag ?? --- SAWMAN
