I just sold off most of my .30-06 rifles down to just one now. I realized I needed to thin down when I looked in my safe and I had six and I'd only ever shot one. I had four Winchester M70 classics (3 FWT, 1 sporter), a JC Higgins FN Mauser, and a Stevens 200. I kept one M70 FWT and rebarreled the sporter to .338-06, and sold the rest off.
I still own three .223's, two each .204 Ruger, .243 Win, .250 Savage, .30-30 Win, .338-06, and .35 Whelen rifles.
