I think there used to be a fella..Carlos Hathcock..that might have disagreed with ya...He shot both weapons...The military stopped using the Winchester after no more CRF....He shot live targets....
Hathcock generally used the standard sniper rifle: the Winchester Model 70 .30-06 caliber rifle with the standard 8-power Unertl scope
Carlos Hathcock had an ability to shoot that most people never have. He could probably do more with a 2 MOA rifle than than most people in the tactical competitions could do with a sub MOA rifle. He had most of his confirmed kills with his M70 but he used a Remington M40 as well as an M2.
As far as M70 being dropped after the CRF went away, by the time Hathcock was in Viet Nam the push feed had been in production for two years. I'll bet the M70's were dropped because of contracting and not because the CRF was no longer available. Remington probably won the bid because during testing it performed at least as well as the Winchester and came in at a price the Military was willing to pay.
My point really was that there are far more options available to make the M700 a target/tactical rifle over the M70. Plus I feel that for the most parts the push feed M70's and M700's operate smoother than the CRF rifles. Plus not everyone has the skills to build their own target rifles like Kraigwy, and the M700 would be a cheaper build than the M70 when you have to pay someone else to do it.
