I think it is a matter of getting used to the recoil. 500nitro you are so correct with, gon't shoot of a bench, the recoil is at least twice than when you are standing. I have a Sako 375 and my daughter weighing only 55 kg is shooting it. Standing she can shoot less than a 2 inch group at 50 meters. If she can do it anybody else can also do it.
