That's the impression I get. So why aren't the barrel makers on the top half of the world getting this right? At some point, they had to make tools or upgrade them. Seems like a good time to switch over or at least add the option.

How's it going to work against coriolis. If shooting south to north you're looking at a target that is moving to the right. If you're shooting north to south you're looking at a target that is moving to the left. West to east, target is moving away, east to west, target moving closer. I don't even figure it in shooting a mile, I think the wind is a bigger factor to be concerned with.
Spin drift? One time has it ever come into play for me. Zero wind, 178 gr out of a .308, 800, 900, 1000 yards, watched the bullet drift right of the target at 800, with a solid zero and not a leaf flickering. Rare conditions.
Just my opinion.
I did hear a tale of a LH twist barrel that was RH threaded into the action. The barrel unscrewed itself from the action. Not totally, but did daylight barrel to action.

JG, go into your ballistics ap. Run the numbers on a load to a thousand yards, with no wind. The drift shown is your spin drift, right? Now edit the firearm to have a left twist, and run the same load with no wind. What does your spin drift show now?
