The 1:14" twist is for use with bullets up to 55 or 60gr. The 12 twist in a 22-250 will get you 63gr.
Twist has less to do with bullet weight and more to do with bullet length than many people want to believe. If you have a 55gr bullet that is shorter than another (Meaning bearing surface) you can use it in a slower twist barrel.
