Mell What is left hand twist?
Also know as S-twist and reverse twist. The fibers in the yarn form the center of the letter “S” moving from lower left to upper right. This is caused from the direction the fibers are twisted into when making the yarn.
What is a right hand twist?
Also known as Z-twist or regular twist. When the yarn is viewed vertically, the fibers in the yarn form the center of the letter “Z” moving from lower left to upper right. This is caused by the direction the fibers are twisted when spun.
What does a left or right twist mean in ballistics?
In a specific barrel, the direction of the rifling can easily be determined by examining the upper half of the bore and observing whether the rifling curves to the left (left twist, counterclockwise) or to the right (right twist, clockwise) as it proceeds away from one’s view.
What is twist in rifling?
Twist rate refers to the rate of spin in the rifle barrel, and is represented in inches per turn. A barrel that is a 1:10” twist means that the rifling will spin the bullet one revolution in 10 inches. The lower the number of the twist, the faster the twist rate or the faster the bullet will spin.
Which way do bullets spin?
As a bullet spins clockwise it will slowly drift to the right, following the same logic if a bullet spins counterclockwise it will slowly drift to the left. This is caused by the bullets axis of rotation and the direction of the velocity vector of the center of gravity deviating as it spins through the air.
What is a gain twist barrel?
“Gain-twist” refers to a form of barrel rifling where the twist rate gets tighter over the length of the barrel. For example, a gain twist barrel might start with 1:12″ twist and finish with 1:8″ twist. Gain-twist rifling is not new. This form of rifling has been around for a long, long time.
What is the difference between a right and left twist bullet?

What is the best rifling twist?
The 1:8 twist barrel is the most versatile of the bunch. This twist rate gives you the most flexibility, effectively stabilizing projectiles up to 80 grains but not over stabilizing lighter ammunition. The 1:9 barrel is best for stabilizing lighter and mid-weight bullets ranging between 45 and 77 grains.
Do bullets spin clockwise?
Do all bullets spin clockwise?
Yes, every bullet fired from that gun will spin the same way, left hand or right hand.. but always the same way. Will every rifle always impart a RH spin on the projectile, no..
Why do guns have a left hand twist barrel?
Interestingly, the Brits USED to think (like the OP I suppose) that right handed shooters usually pull their shots to the right a bit, and that a left hand twist to the rifling will minimize the effect. Not so, but it was a quaint idea. So, by convention, most modern gun barrels have right hand twist.
What kind of rifle has a left hand twist?
The only rifles that I know of that had left hand twist was the 303 Lee Enfield. Left hand twist unscrewing a barrel not likely it would actually tighten the barrel if any. Look down the rifle from the but end the twist rotates in the same direction as tightening the barrel into the action.

There has always been the debate about right hand rifling loosening the barrel. If torqued correctly this will not happen. but if the barrel is installed hand tight it is very possible. Many European countries believe in left hand twist for one reason or another and still use them.
Why are gun rifling twist directions usually right-handed?
If you chose A, you are correct in the reasoning why the Brits initially gave their guns left-handed twist. But is the theory true? There is no real reason for the twists of gun rifling being right or left handed these days—except for tradition.
