Bobdahunter: I have three collector quality pre-64 Winchester Model 70's in caliber 308 Winchester - all are Featherweight Models.
Just returned from a 3 day gunshow in an adjacent state and indeed there were NO pre-64 Winchester Model 70's in caliber 308 Winchester there for sale!
I do know this - most all 308's got put to use by Hunters and shooters and collector quality 308's (in any configuration) are rare to find nowadays and for some time now.
Indeed the same holds true for Rifles in 270 Winchester caliber - they got USED - it was VERY difficult for me to find/settle on a mint condition 270 Winchester Featherweight for my collection.
Long live the Riflemans Rifle.
Hold into the wind
