I've had an on and off relationship with collecting everything for the past 10+ years now... There was about. A year that I didn't have a 30-06 in the past 18 years. I've had a 257 weatherby since 2006 so that would put it right about 10 years now... Also bought a 30-06 when the M70's came back in 2007, so its also pushing 8+ in my safe...
Longest prior to that was my 50 AE desert eagle, but with all the crap with the swiss arms and figuring we were going to have a liberal or dipper govt got me nervous, so I traded it last year around this time.
