US made rifles have a clockwise twist on barrel threads and a clockwise twist on lands and grooves. There are European rifles that have counterclock wise threads and counterclock wise lands and grooves. If a barrel with clockwise lands and grooves was installed on an action with counterclock wise threads would the barrel eventually shoot loose?

Maybe

Well, now, I have personally seen and worked on EGG-FAWKING-ZACKERY, 17 gabbafrackinbazzillion British Lee Enfield 303 rifles with left hand twist and right hand threads over 35 years of professional gunsmithing and I have never seen one shoot loose. So I'd have to side with Farner and say (Maybe). But I ain't holding my breath.

The British are sort of magical with guns though.

yabut what if you went down under would that still apply, cause the water reverses direction going down the drain.

Well, the reason for my question is I have a wonderful Austrian made barrel in .243 with counterclock wise rifling and counterclock wise threads that I have installed on my Norwegian Krag (lite load ofcourse) but it will not feed properly. I am a nut about feeding. I have always sold off anything that would jam, or skip a round. This Krag feeds 6.5X55. 6.5X57. 7X57 amd 6mm Remington beautifully. I have barrels in all the above , with right hand twist that could be threaded to the Krag----should I?

You have way too much time on your hands. Install the barrel.

Colt pistols and most other 1911's have left hand rifling sooo......

Yabuts are in the bush !
Won't make a difference. No season for toilets in Australia. Also, most toilets are shot with the rifle held horizontal. Vertical toilet shooting is messy and sometimes dangerous. Not advisable and rather unsportsmanlike.

I have barreled a few Norwegian Krags with right hand twist barrels and have heard of none coming off. Of course, there is always the possibility that the rifle failed as a result and the shooter was killed and that is why I never heard but I kind of doubt it. Regards, Bill

I'm suddenly weighing the possibilities of doing a few Danish Krags for a few of my customers here Billy.

OH MY ! I shouldn't think like that. That would be BAD!

Thanks for this reply Bill, which was exactly what I wanted. Folks with 5368 posts are true experts on too much time.

there are a number of custom barrelmakers that offer them.

www.bartleinbarrels.com offers pretty much any twist you want, left or right handed, even gain twist. They are cut rifles. I have a 6.5mm barrel on order from them. I specified left hand twist and a 1:9 to 1:8" gain twist. The notion is there to counteract the Coriolis Effect.

I read all of Brian Litz's books and spoke with him before ordering. Does talking to an expert make me one, or do I have to stay at a Holiday Inn the night before?

They will un-screw if the barrel is not tightened up to specs. When I was stationed in northern New Mexico a fella brought me a 1917 Enfield Rifle in 30-06. He had purchased it years ago and someone re-barreled it. To get the front sight to index properly, they took a center punch and put some dimples in barrel where it contacted the front of the receiver. After a few boxes of cartridges over time the dimples flattened out and the barrel began to un-screw. That is the only one I ever saw or heard of un-screwing. It simply was not tightened up properly. Should have been faced off a little less than one thread, torqued up to specs and the chamber deepened to specs.

Due to Coriolis Effect CCW rifling will cause bullets to rise rather than drop, causing a need for hold-under. This is counter-intuitive for American shooters.
