Thompson Center a long established name in muzzle loaders and single shooters is later entry in the bolt gun market. Before I bought a chassis gun I would wear out the long range shooting forums, read on-line reviews etc. Begara is a new name getting a reputation. 6.5mm Creedmore is a relatively new cartridge gaing popularity.
I would not put too much "economy" thinking into this proposition if you are planning to be a competent 1,000 yard marksman.
