100-400 USD
Sounds like you have a Remington Model 700 chambered in 264 Winchester Magnum. The 700 was made in 264 Win Mag from 1962 - 1977 and again for the 1986 Classic. Go here for a little history - http://www.chuckhawks.com/264mag.htm http://en.wikipedia.org/wiki/.264_Winchester_Magnum
A Winchester model 70 XTR which was made in 1979 will bring between 350-500 dollars depending on overall condition,and that the bore is not eroded.this happens in a rifle with a serious overbore cartridge such as a 264 Win mag.
Very little... Winchester did not introduce the 264 Winchester magnum cartridge until the year 1958. If your Model 70 is actually a 1955 vintage rifle, it is not factory original.
