As a lefty shooter, I prefer the right action in left stock. I use aftermarket stocks for 3 of my guns and 1 has a lefty beech stock with the notch for the right handed action cut out. I wouldn't cut up a walnut stock, so I by custom made. I have 1 full lefty and it is a joy to shoot and load. I'm right handed, so I cock with the right and load with the left on the lefty gun. Very efficient. I also shoot full right handed guns and have no problem. Some seem to have trouble with the top edge of the wrong sided stock, but I don't even notice.
