For what it is worth. Warren Page used an early (1950 +/-) Rem 721 as the basis for his .375 Weatherby and eventually had it rebarreled 2 or 3 times. It NEVER failed him. Read his 1969 article about it. Ross Seifried used a Rem 700 .416 for years. Both are push feed. Ross thinks it is much ado about nothing.
Both guys have/had a great amount of experience.
