https://www.gunbroker.com/item/902570732 There are no factory records or even anecdotal tales of Sako producing a rifle stamped "6mm Remington", but here is one being offered, and in the Deluxe version. The six-digit serial number on the action (which is a very late L579 with the A-II shrouded bolt) indicates the late run of L579's in the late 1970's before the changeover to the A-II designation. All of the Sakos chambered for this cartridge, so far as we know, were labeled ".244 Rem" and were from the late 1950's into the early 1960's prior to Remington changing the name of the cartridge and quickening its standard twist. The stock configuration of the rifle is the high, sharp comb version of the early A-series, which would be consistent with the rifle's serial number in the 300,000's. But, looking at the caliber stamp, I believe that it is an attempt at making a barrel stamp that closely mimics a factory Sako barrel stamp. However, the font is not just right and the stamping is further forward of the receiver ring than the factory stampings. It is my belief that someone went to a lot of trouble to make a Deluxe Sako which appears factory in a caliber which the factory has never been known to have chambered. However, there are some one-off Sakos floating around and we "never say 'never' with Sako". Would be interested in the opinions of others.
