Mine would have to be my Winchester Model 70 Sporter Varmint with 26 inch barrel in .243 caliber.
I had one just like it when I got divorced but had to sell it to pay lawyers...mine and hers.
The original put down a lot of deer. I hope the new one will too. It has taken me 15 years to find this one because not many were made.
This one is more accurate than the one I had to sell.
Update after deer season. 11/19/08 at a range of 200 yards, my Winchester and me took a nice button buck with one shot. Bang/flop. This one is a winner.
