Found these two websites, they look legit enough and today after work I am going to dad's to grab the 700-.30-06 and going to test it out!! I'm anxious to see when this rifle was mfg'd. Remington Society of America - questions/barrelcodes ^ The above link shows how to date your rifle by barrel codes, we'll see what it shows on my .30-06 today. Remington Society of America - questions/FR01 ^ The other link above shows a scanned book of Remington Rifles and shotguns by date. I will try the barrel code way first and then test it against this method!
