RE: 243 vs. 25-06
The Tikka in 25-06 is a good choice. However, I just sold mine last year. It was a good shooter and I had a VXIII 2.5-8 X 36 on it. Great combo. I did not care for the 2 position safety and not being able to cycle the bolt to unload on safety. Other than that I'm sure you'll like it's effectiveness. Good luck.
