I purchased a used Tikka 243 cal in 99% condition. As with most used firearms I purchase, I disassemble the firearm to further examine the inside area. I noticed the inside of the stock appeared to be light colored birch instead of walnut as advertised on Tikka's website. The wood was also softer than most walnut that I have seen and used. Does anyone have any expertise inregard to the Tikka T3. Thanks
