From a bit of Googlefu, 'the model 71, the Canadian version of the model 70 made in 1966'. So, you are asking about an off-label post-64 Win Mod 70 in an odd cartridge. The .225 Win is an orphan cartridge, comparable to the .223 Rem, SWAG - $350 to $400.
I saw a good to very good condition Cooey 225 go in the $700 range at a recent auction. There are guys out there that love their Cooeys and the centerfires don’t come along as often as a model 75. That being said, as obsolete cartridges go, the 225 chambered Cooeys seem to come along more often than some of the other centerfire offerings.
Actually, I have a 225 in a better rifle, but it is NOT comparable to the 223, It is much closer to the 22-250, and as such is a respectable performer.
The Model 71 sports a M70 type bolt, but without the safety on the bolt. The receiver is round, with the Remington 700 type of recoil lug, so M70 stocks do not fit.
As this poster intimates, though, the 225 is an orphan, but with brass and dies [available] has use in the varmint field. Value as he suggested is pretty close, IMHO. Dave.
