Off the point, but I used to have a M1B chambered from SA in .308
Recoil on that one was a real *****cat. Rifle was heavy enough to absorb almost all of the recoil.
Anyway, it was a "Navy" special, believe it was made for the rifle team, but not sure. anyway, it was a beaut... like most things in life, looking backward I should've never let that one go... but que'cera
