Anyone try a Left twist?

[Mr.Knowit all]

Hello,
So all my guns have RT but I can get a good deal on a LT and I started to run the numbers to see how Spin drift would change. Some guys like to use them to help with the Coriolis effect in the Northern hemisphere. I don't know...?
Anyone have any advice on LT? Does it really matter? A lot of ballistic calculators don't even have a place to input Spin drift.
Thank you

90% of my barrels are left twist Chanlynn.
Does it make a difference? No.
Good barrel is a good barrel. It hurts me when shooting a match with a bunch of righty boys. Their hold will be different.
The further out you go, the more you'll notice.

It shouldn't matter a bit and will help negate the coriolis effect as you say. I think it will cut spin drift by about half.

I have one. Aside from my gyroscopic direction change, I don't even think about it. I inherited the rifle/barrel and there was some talk of the rifle rolling into or away from my face of some such. All I know is that it shoots. Really well. Which has nothing to do with the direction of the twist.

I have yet to see someone demonstrate that a left twist rifle will roll into a right handed shooter. I think Dave Tooley has said that basic physics says the opposite will happen in another thread that I have read.

Spin drift and coriolis are such minor concerns that you can virtually ignore them. Typically, if I do anything, I will dial for spin-drift and coriolis, and then hold for wind. In reality, I usually just shoot from 0-1000 yards with .1 mil of left wind left on the gun. Even for longer distances, I'll just dial roughly .1 for every 500 yards past 1000.

I plugged left vs right twist in a calculator a while back. I think the total difference was having to dial .2 left for 1000, or .14/5-ish right for a left twist barrel.
