I am putting on a 1-12.It will do what I want done. I have zero use for heavy bullets at low speed in a .22 caliber.
Nothing wrong with a 12 twist have had several but even for 50s or 55s a 9 wouldn't be a bad deal.
A 53 V-Max in a 9 twist would give a pretty good splatter factor.
Fast twist doesn't mean you have to shoot heavies, just opens up that door.
