Honestly assess your shooting. Is your ammo as good as the gun? Is your ability as good as the gun? I say this because many will argue that the Vanguards are every bit the gun the Tikka is.
The Tikka would be a very solid buy. It might not be as pretty as some rifles, it might not have the broad acceptance of some brands. You will never be ashamed of it's shooting performance, end of the story there. I have one in .300WM and it makes me smile every time I walk down to the 300 yard berm. It will consistently put rounds into a CD. Now that may not impress some folks but that is way beyond my expectations of what I'm capable of. It does this with Federal Nosler Partitions, Winchester Failsafes, and Remington Corelokt. It has shot multiple groups with each of them, not flukes by any means.
