Just curious to know...

It's a matter of tooling. It's abritrary. Motors, engines, drills, rope, threads, - all such things are made with a "twist" that matches the tools that made them or the tools that will use them. Manufacturers attempt to keep the world "standard" and uniform so somewhere back there they found it easiest to set the twist right hand and they have just kept it that way.
 
Actions and barrel tenons are right hand threads as those are easier to make on the machines typically designed for use by right handed machinists. [Note that up until well into the 20th century it was considered unacceptable in most cultures to be left handed.]

With right handed threads in both the action and on the barrel tenon, each shot will produce a torque reaction to the bullet being spun by the right handed twist that will tend to tighten the barrel. A left handed twist would produce a torque reaction to the shot that would tend to loosen the barrel for right handed tenon and action threads.

Why most majority of rifle barrels are in right twist? :confused:

Okay here are the top 10 reasons most barrels have a right twist.
Drum roll please.

1. Most barrel makers are right handed.
2. Most shooters are right handed.
3. Barrel makers discriminate against left hand bullets.
4. Remember righty tighty,lefty loosey.
5. Left twist will unscrew your barrel.
6. Works better than straght rifeling.
7. Works better than no rifeling.
8. Tells bullet which way to turn, eleminating confused
bullet.
9. Since the earth rotates clockwise when facing north
and most ranges face north fireing a left twist would
negate the rotation of the earth.
10. It just don't matter.

Left hand rifling twist...

I don't have an answer for "why" most of the rifle barrels have right hand twist, but I once purchased a heavy match grade .22 rimfire barrel in "left hand" twist...IT WAS a BUMMER not a HUMMER...I don't know why but it shot as poorly a factory std weight barrel..:mad:
 
twist

Bo Clerke is a long time barrel maker and one of the most intelligent individuals I have had the previlige to know. He has done bunches of barrels and testing thereof for the military. There IS an advantage of RH twist in the northern hemisphere, and LH twist in the southern hemisphere, but in the small arms world, the numbers are "in the dirt" as he says. According to Bo, the large weapons (cannons, tank guns etc.) than shoot a ranges far exceeding small arms, the numbers come into play to the extent that the military actually uses the appropriate twist direction in each hemisphere.
There is a formula for this that he keeps handy, but again, the advantage is only seen in the LLLLOOOOOOOOOOONNNNNNNGGGGGGGGGGGGGGG range artilery.

There is a DIFFERENCE but no ADVANTAGE. The effects of right hand or left hand twist are the same, they are just reversed in one hemisphere as compared to the other.
 
schucks, if any you'se guys wanna' test it just turn your barrels around, chamber the muzzle end. The Ozzies do it all the time to combat the Coriolus reversal..... :cool:

duhhh.....

I tried that with a windflag daisy so it would turn the other direction. That's about the dumbest feelin' I ever had short of holding backwards.
