Ithaca LSA 55 is the same as the Tikka only imported by Ithaca in the 70's. Hard to beat for quality and performance. I think $600 is low on price now. Most of the ones I see for sale are $800- $1000. Once you get on to the selector and the hammer, it is pretty quick.
The Ithaca LSA 55 and LSA 65 models are magazine fed bolt action rifles. I had one in 25.06 and couldn't find an extra magazine for it.
