Thanks for the feedback. I've seen a lot of support for Tikka and they seem a little more cheapley made the few times I've held them.
The Browning X-Bolts are single stack.
In which areas? The action assembly is slick and smooth. Some folks didn't like the T3 plastic bolt shroud (I didn't care personally) but that is metal on the T3x. The stock feels nicer than most other factory synthetic stocks (the T3x feels better than the T3 by the way), so short of going for an expensive composite stock at a different price point gun I can't ask for more there (I personally have no interest in a wood stock rifle for the hunting I do). Finally you're at the plastic mags/bottom metal. I've never had a concern with them but those are also replaceable if really bothersome, it saves cost/weight while being perfectly functional and not clunky feeling (in my opinion, esp. compared to some of the actual budget rifles out there).
Browning I kinda lump in with Remmington, they seem like they are still trying to ride the wave of brand recognition of the past. What is the murmur on the x-bolt in terms of accuracy? I can't say I've really heard all that much either way.
