Looking at getting a couple Tikka t1x rifles. between the kids and I there's a couple left handed shooters and right hand shooters. Between getting a couple parts, swapping some barrels, etc, my question is if I bought a left hand in 17hmr is the bolt different to a 22lr if I wanted to swap a barrel or buy an aftermarket barrel. Also if it's just the extractor to change, I'd assume the left hand and right hand extractors are the same and simply different between Hmr and .22lr.
