If memory serves me right, weren't the guns Remington chambered in 7x57, built on SA? The SA IMHO puts a 'hamstring' on the 7x57.
I've had (still possess one) 3 rifles chambered in 7x57. An Interarms MK X, which was a long action, a Win 70 (SHOT Show Special) that was on a SA, and a Ruger 77 Tang safety which is built on a LA. Of note, the current Win 70 SA is just a tad longer that the Rem 700, and doesn't 'hamstring' the 7x57 like other SAs.
