"Tradition" perhaps? Same reason why the 22-250 carries a 1:14, which seems to be because that twist is optimized for bullets lighter than 55 grs which were what was originally used.
There remains a belief that twists faster than 1:9 will "over stabilize" the 55 gr and lighter bullets.
Andy....
Many years ago I stumbled upon a take off 1 in 9” twist Remmy M700 SPS tac 20” Barrel at Rick’s shop (ATRS). I took it to Elwood Epps shop and they installed and rechambered that rig to 22-250 in hopes that I could launch Sierra 69 grain MK booolts at NSCC in Connaught Ranges.
I tried out that combination in the Ottawa Valley on bilingual groundhogs with phenomenal success. Launched several of them towards Arnprior. Hahahahaha I could tell they were bilingual since I wore amplifying ear muffs I swear I could hear the Holy Calis Taber....you know the rest!
A buddy of mine from the Durham Maxwell are of Grey County wanted it so badly for his groundhogs and other misadventures, he made me an offer I could not resist. It was a wonderful experiment,
9” twist Remmy SPS Tac in 22-250....who woulda thought?
