WITUfan,
If you remove the factory pad and install a slip-on Limbsaver, you should be able to withstand the recoil for a few shots, but be advised, light rifles are just plain harder to shoot, and the Tikka certainly falls in this category. You may need to refine your technique, especially relative to shooting from field positions. My T3 is in .270 Win. and I shoot a lot, and it is fine. A Tikka .300 mag. would (for me) bring out the shooting jacket, gloves, and sandbags.
You can fill the hollow buttstock with something, but the rifle will then be butt-heavy and poorly balanced (as well as weigh more).
