In relation to firearms, it has to do with the rate of rifling in the barrel. Rifling is the spiral grooves that puts a spin on a bullet to increase it's accuracy. "Barrel twist" is the rate of spiraling or inches per turn. That is the length of barrel it takes to spin the bullet a full 360 degrees.
Impossible to answer without knowing the caliber.
The twist rate in a Winchester 670, 243 caliber is 1:10.
