Left twist barrel for a left hand shooter

I shot lefthand for over 40 years in the prone position and never wondered about torque of the rifle if you are in a sling correctly. I believe if you have to worry about twist torque you aren't in the sling correctly... remember keep them in the center of the target...
Nothing a welder couldn't fix...

You are supposed to run left hand twist barrels in the Southern Hemisphere to match the direction that water turns when going down the drain.

Very true.
When I went to Australia and South Africa to shoot long range matches, the locals offered to reverse twist all the USA team barrels. They said a forge was next to the range that heated up barrels red hot. They next would be clamped at each end in a precision hydraulic twister to twist them breech end clockwise to make left hand style rifling. After the matches were over, they would reheat then retwist them back to right hand. All at no cost to us but just a friendly gesture.
I chose not to do that in South Africa. Instead, I had a local 'smith thread and chamber my barrel's muzzle end, then put that end into my action. That did the same thing and did not chance changing bore and groove diameters. Made the rifle more muzzle heavy but otherwise shot very good.
Then reversed the barrel in the receiver upon getting bank to the USA.

Mmm, in Palma with sling and irons I already group almost all inside the 10 ring and in average 60% inside the X ring (10 ring is 2moa and X ring is 1 moa with distances from 300y back to 1000y). Very rarely I will drop a 9 (lately one 9 every fortnight shooting twice/week).
In ISSF 300m prone I have been averaging 199.8. (the 10 ring is 4" and the X ring is 2").
My issue is a small amount of left sway in my recoil pattern imparted by the twist of the barrel which I reckon it must open my groups somewhat.
This forum has been my prime and only source of information on how to reload and tune my rifle.
The likes of Boyd Allen, Joe Salt and Erik Cortina just to name a few of many have taught me so much just by posting here their knowledge.
I'm currently geared for the 2019 World Long Range Championships in New Zealand and I must make every effort to maximize my grouping potential.
Do you need to use any kind of thread lock liquid?
Same situation when you put a right hand iron sight reversed on a left handed rifle and you then need to screw the knobs the other way around...
Right hand twists have been used by left and right handed people shooting equal winning and record setting scores in position matches. It's a constant, not a variable in the shooting system. That twist is easily seen with scope sights.
Never heard of anyone concerned about it until now. Therefore, I don't think it's a problem. But do what makes you feel best. Nobody shoots better than they feel.
Many years ago, I was shooting in a long range shooting class that followed the regular competition at Camp Perry. We were shooting a match at the end of the class. One of the shooters kept having windage adjustment troubles. His elevation adjustments were changing a bit also. He fought it for several shots. Then, he went to fire another shot and his front sight was sitting at 9 o'clock. Further inspection revealed that his sight base was firmly attached to his barrel. He could hand tighten his barrel and it came almost tight enough to get his front sight back up straight. He did not fire the rest of the match. Could this be an example of a left hand rifled barrel rearing it's ugly head?
If YOU put all of your bullets in the middle of the target, THEY have to give you more points.

I've seen two instances of loose barrels on rifles at matches.
Torqued in properly, they won't unscrew from bullet induced torque
Left twist barrels. I now have two, run in and tuned.
I now know that its a major game changer for me , being left handed.
With a right twist barrel, my muzzle jump was a small, counter clockwise loop.
With a left twist barrel, my recoil pattern is straight back with negligible upwards motion (sling and irons). Under recoil, the target frame barely leaves my front tunnel and witnesses say that they cannot see noticeable upwards motion.

Grinders and welders work wonders when a firearm needs "fixin'".

Heck, I once knew a welder that could weld anything but a broken heart or the crack of dawn.
