Lord, that's a tough decision for me to make. These are the five I use 90% of the time:
Win M70 Classic Stainless in .308 Win. w/Leup VXIII 1.75-6
Sako Finnbear (early 1968 vintage) in .30-06 w/Sightron II 3-9
Ruger Tang Safety M77R in .280 Rem. w/Leup VXIII 3.5-10 x 50 and Brown Precision Kevlar & Graphite stock
Ruger Tang Safety M77RL UltraLight in .250 Savage w/Leup VXIII 2.5-8
FN Mauser (mid 60's vintage) in .270 Win. w/Tasco World Class Plus 3-9 (a good scope believe it or not)
I somehow managed to hang onto these through a nasty divorce, so they truly mean a lot to me.
If I had to choose one and only one, I guess I would put the Leupy 2.5-8 on the FN and keep it. Or would it be the Ruger .280?

It's too hard of a decision!!!! My brain is aching!!!
