depends on the rifle old M16s used to have 1:12 this was designed to stabilize 55gr projectiles in arctic conditions, or regular conditions for that matter. Now-a-days....were using heavier bullets. 55 and 69 grain projectiles. m193 and m855. The military commonly uses 1:7 twist rate. My RRA rifle has a 1:9 twist rate and I haven't found a bullet it wont stabilize. I have shot 75 gr. (too big to feed from the mag) and a 40 gr v-max. I dont want to go heavier or lighter...so 1:9 is perfect for me.
The Springfield 1903 has a 1" in 10" twist rate. The later M1 service rifle also has a 1" in 10" twist rate.

The standard rate of twist for a .22LR firearm is 1 turn in 16 inches. I don't know why a Remington 541 target rifle would be any different than 1:16

Always refer to the manufacturer's specifications for the exact twist rate corresponding to your specific X-Bolt model and caliber.
