I'm admittedly COC prejudiced (Duh - Ya think! :)) Yet most of my bolts are COO since particularly in sporting context, such the way of the world in respect of my primary interests through the seventies era and again in the nineties in context of the FN production era of Winchester Classic CRF line. The COO or COC really does come down to personal preference/prejudice.

A short side note concerning the Schultz & Larsen rifle mentioned above. A Danish firm making high quality rifles as unable to achieve the production numbers to be competitive in the American market as principally targeted in the fifties under Phil Sharpe as importer or the sixties under the mighty Norma Precision Firm backing. The S&L, An expensive rifle of aft lug locking design and even to date perhaps moved from largely "unknown" to largely "past era exotic". The first models of the fifties were COC, a transitional model and wrapping with two COO models in sixties era.

With the milsurp market of the American fifties, the COC action was established as 'almost exclusively' associated with military design and surplus context. The interwar Remington Model 30 earlier years were the proliferant COC design featuring the civilianized Model 17 Enfield action. To my tastes, great rifles. The S&L were exotically partially hand-crafted, of great quality of materials and workmanship. I congratulate anyone owning one! I have five, all acquired as "also ran unknowns" and such prices reflected!

Thanks those of you who put up with another dissertation! smile
Best!
