Here's a Sako L57 action as stocked and barreled by High Standard for Colt and marketed as a "Coltsman." It's a .243 Winchester and it will keep five shots inside of an inch at 100 yards with my handloads. This came with the Sako medium rings, and a Lyman 6X All-American scope fits perfectly with no more than 1/16-inch clearance to the barrel. These actions are getting very hard to find as only a very small production run of 10,090 were made between Jan. 1, 1957, and Oct. 9, 1959. It was replaced with a revised version, the L579 which, as usual, was cheapened in the process. Extremely well machined and finished, these push-feed actions are incredibly slick. They are also lightweight and have a smaller diameter bolt than is typical for either the .243 or .308 cartridge head.
