Right handed, left eye dominant. I shoot handguns right handed but use my left eye, so my wrist is cocked a little. I shoot long guns left handed. Both of my brothers are the same way.
I'm pretty accustomed to right handed long guns. For bolt guns I keep my left hand on the wrist and work the bolt with my right. Sometimes I have to move my left thumb out of the way. Autos, pumps and levers are pretty easy. I'm accustomed to brass flying past my face.
Still, I do have a few left handed bolt actions. Even though I already have a left-handed CZ452 American, I just went on GB and bought a left-handed Savage Mark II G just because it's so darn inexpensive. Photo from GB listing. The listed price was $250 with no credit card fee AND free shipping, so after taxes and my FFL's fee I'll be into it for $290.
Besides the Savage and the aforementioned CZ, my first left handed bolt gun is a .460 Weatherby with Lazermark stock. Great fun.
My target of choice is a one-gallon can of hominy corn at about 20 yards.
Then I have a couple of lefty Ruger M77 Hawkeyes, one in .308 and one .223. I haven't shot either one much yet, even though I've had them for about ten years.
