I wouldn't hold my breath for the FAL chambered in 7x57 to be selected. Don't get me wrong, I like the FAL. I've shot my son's often. I love the 7x57 and I have 2 rifles I chambered in 7X57. One issue is the 7X57 is an old design with a max SAAMI pressure of 51,000 psi. Modern cartridges, like the 6.5 Creedmoor are rated to 62,000. That allows cartridges to be smaller/lighter and still be more powerful. I'm partial to the 6.5s. I have 2. A 6.5x47 Lapua, I've bagged several deer and hogs with. And a 6.5 Grendel that I shoot in my AR. I can shoot the same 140gr bullet I load in the 6.5x47, just a couple hundred fps slower.
