The Remington 725 was the last model of the 700 series that had "Cut Rifled" barrels or so I'm told.
That’s interesting. Wonder where I could look that up.
I read that cut rifle barrel info in an article years ago...would be interesting to really verify.
All model 721, 722, 725 & 700 barrels were produced using the Mike Walker developed "Button Rifled" process until 1967-1968 , when Remington started to use European "Hammer Forging" technology.
