who makes rifles with left twist bbl?

Theoretically a right hand twist will tend to tighten when subjected to impact and torque. A left hand would do the opposite. Whether it would or not, I don't know, but we shoot-off drill-pipe on the rigs routinely using a small charge and reverse torque.
I had a Al Pederson LH barrel in .270 Winchester. It was a miserable fouling pipe, but shot very well when clean. Shoot for an hour, clean for a week.
That never had anything to do with the left hand twist though.

The whole thing got in the rifles as well, and I was very intrigued by this affirmation.
I would have thought that it has something to do with the effects of the polarized light turned to right (dextrogir)...or maybe with the momentum definition in early phisics... teh energy and the right hand rule,
Maybe the only logical explanation would have been the thread direction on the bbl @ receiver.
Thank you , and if you think of anything else that might have determined this so wide acceptance, please post it.

Of course the barrels are torqued tighter than the little bit of bullet induced torque. Otherwise it would be darn hard to hold onto a rifle whenever you fired it!
What I'm speculating (and it's only speculating) is based on a procedure we use on the oil rigs a lot. When your drill-pipe are stuck in the hole, there are times when the best course of action is the unscrew a joint down-hole at a predetermined spot. This is how it works; a small amount of reverse torque is placed in the entire drill-string, then a small powder charge is run down the inside of the pipe on a wire line to exactly the joint where you want to back out of your threads. The amount of reverse torque applied is a fraction of what the joint was made up to originally, yet when the charge is remotely triggered the shock wave causes it back out at that spot. It seems to work everytime, at least I have never seen it fail to work. I doubt that a barrel would back out, but this is a situation where a small controlled blast is also happening at precisely on a threaded fitting with a small amount of torque also being applied. Maybe someone thought that it was better to be safe than sorry? Just a thought.
