Just went out to shoot my New Henry H001TM 22mag for the first time and it key holed several brands of 30gr 2200fps ammo Remington and CCI and the Winchester Dynapoint in 45gr it was like a shotgun instead of a rifle

what gives? Does anyone know what the twist rate is in this rifle and why would it be keyholeing the 30 grainers at 25yds?
