RE: Which rifle?
Tikka's are generally great shooters but, the ones I've shot at the range in that caliber, kicked like a mule. I have a Tikka stainless synthetic but it's only in 25 / 06 so that doesn't help much in this situation. I think the Browning is probably a better built quality rifle so I'd vote for the NIB Browning. I'd also look at Rugers as they are well built also.
