We're all different.
I'm left handed, right eye dominant, shoot right handed. However I've always naturally picked up a rifle right handed anyway so it has never been something I thought about until recent years. I also do archery with a right handed bow.
On the other hand
I'm completely incapable of writing with my right hand, but I naturally use a computer mouse in the right hand. In cricket at school I used to bat right handed but bowl left handed and I use the cue in pool, snooker etc left handed. If I was chopping down a tree (not something I've ever done) I'd want to hold the axe right handed.
I can shoot a pistol with either hand and I seem to be able to use left eye/left hand but I'm much better right handed.
Hell no wonder I'm so screwed up!
