Probably IOF found 1Turn/304.8 mm to be the optimal twist rate for Anmol. There are various factors that decide the optimal spin rate for a bullet, one of them also being the muzzle velocity of bullet. Since Anmol has slightly longer barrel, the bullet would have slightly higher muzzle velocity, hence the difference in optimal twist rate.
