I can confirm that water definitely goes down the plug hole counter clockwise.
What has that got to do with shooting?
Answer is direction of rifling might have to be reversed between North and South hemisphere.
Can someone take a look?
In UK what direction of rotation does water do going down the plughole?!!!
Just another of my crazy questions!
 
Does direction of rifling affect verticle poi depending on which way the wind is blowing though?

If rifling is clockwise and the wind is blowing from the right to the left the wind is catching the pellet on the right side which is rotating downward at that side... Could this give the pellet a bit of lift? And if so, the opposite(s) would also be true, so with clockwise rifling if the wind were blowing from left to right the wind could maybe 'catch' the pellet on the side facing the wind a bit more than the other side that is facing away from the wind direction thus giving it a bit of a downward push. That's opposites of wind directions, opposite again if opposite rifling direction.

Years ago I used to think there was some truth in the above but I'm not sure how much sense it makes in a ballistics / physics sense and I now think the 'effects' I were noting were probably more due to something else, not least my aiming hehe.

What do others think?

With rifling? I doubt it's different.
The battle of Rourkes Drift (Zulu) was won with British made rifles, I assume BSA or Enfield. Plus, I have a friend in Yorkshire who's son went to SA and won gold in a long range shooting contest, he took an Accuracy International with him.

I seem to remember something about sights having to be replaced to allow for use in the Southern hemisphere?

Fill the sink, turn the tap off then pull the plug. Why do folk have to be difficult?.

Do you know the cost of water in the UK right now! I'm not wasting a litre or two, plus it's probably a climate crime!

I wish, so much, that was parody.

I used to work with a guy who shot rimfires competively.

He did say that you have to allow differently depending on which way the wind was blowing due to the rotation of the bullet.

Isandlwana was lost with the same rifles!
 
Is there not one forum member prepared to be merciful and generous and at least watch the plug hole after you have taken a bath or, heaven help us, washed up? These replies are taking the Mick from a serious question.!

I did have a go but inconclusive.
The first time it looked to be clockwise.
The second time I let it dwell for a lot longer, in case there was residual movement from filling.
There was a swirl but the water was so calm it was hard to see the direction.

So the question requires, fill, dwell time, something in the water to look for movement, careful extraction of the plug, then enough form to the spiral to identify the direction.
So aside from the levity it's a slightly harder task with an normal tap and sink to be conclusive (in the time I could be arsed to donate).

yeah but everything is backward in narfook

do you actually have running water

Irrelevant which hand rifling is. As long as the projectile spins thats what matters otherwise it goes all over the place like a ball from smooth barrelled musket.
