I own a Tikka T3 Tactical in .308 and love it. Just put a Elite 4200 6x24x50 on it and shot this:
3 shots, 100yds, bipod prone shooting, no sandbag. Tight enough for you?
As has been said, while I would not dispute the quality and proven track record of the Rem 700, you do have to put a lot of work into that platform. If you're a fiddler, great. Me, I bought my gun, put a scope on it, zero'd it, sighted her in and adjusted the trigger pull myself, adjusted the cheek weld with the factory built in one and put a Sako comp on it for good measure. She's as good for hunting as she is for shooting paper.
1) You are stuck with the Tikka stock. The recoil lug is actually in the stock, not on the juction between barrel and action. This makes after market stocks non-existent and it makes bedding them a bit more of a challenge.
Not so. Contact Joel Russo at
jkrussos@comcast.net . He makes aftermarket CNC wood laminate stocks, including ones for the T3. His work is beautiful. Me, I am happy with the tactical look and the factory stock, but YMMV.
2) The action contour tapers sharply down to a barrel that is narrower than the action itself. This limits the barrel contour to the same diameter as the factory barrel if you wanted to customize.
Sorry, customize what aspect of the gun?
If you want a "tactical" rifle with good qualities and lots of growth potential, look at the police models in the Remington or Savage lines. They are cheaper and the possibilities are almost endless in terms of japing them up.
The basic platform is cheaper but rapidly approaches and surpasses the Tikka. If you're into fiddling, by all means.
These two Tikka proprietary design issues mean that you're basically stuck with the factory rifle; other than optics, brakes and ammo, there is not much you can change easily. That isn't neccessarily a bad thing, but I wanted to change a few things and it was basically too expensive and difficult to be practical.
What did you want to change? You can thread your own comps, your built in rail lets you accessorize, it takes standard attachments like bipods, you can modify the stock if you wish (I've seen some interesting attachments made by members here when at the range) or get a whole new laminate stock altogether.
Sounds to me like you're fiddly (no disrespect intended), which means you probably are better off with a Savage or Remington in order to scratch that modification itch. For me though the gun is everything I wanted without the hassle or expertise required to go out and build out the platform.
The only itch I have is custom ammo, which I build and shoot, so my itch is easily scratched without cutting into the rifle itself.
