I owned a Tikka T3 243 for about 5 years and shot the barrel out of it, roughly 4500 rounds thru it. I purchased a brand new Tikka T3 Lite 243 last week, I will be scoping it today and sighting it in. They are excellent firearms and are very accurate, with a great user-friendly ajustable trigger.

As for optics, the Nikon Buckmasters is a great optic for a pretty good price. If not the Buckmaster I would step into a Leupold VX-II. I have no experience with the Bushnell higher end optics, but will strongly reccomend staying away from their "Trophy" series. Zeiss are great scopes as well, I have one, but I'm not sure its worth the extra costs over the Leupold VX-IIs, and I'm not sure its any better than any of my Leupold VX-IIIs.
