Sorry, but I can not locate any information on Krico barrel twists. 95% of new 22 rimfire barrels have a 1-16 twist. This is for both the long rifle and magnum barrels.
Hart, Shilen and Shaw all have a 16 twist on their rimfire barrel blanks, Lilja is available with a 17 twist for magnums. I have also come across some 15 twists, but they are rare.
Douglas has from 13 to 17 twists on their blanks.
