Like someone else here, I would prefer to sight in at 35 yds. thinking that is probably the optimum range. However my club only has 25 & 50-yd ranges and our rules require that you shoot only from the bench and at targets only on the backstop. I therefore sight all my .22s in at 50-yds. I use exclusively 1" diameter big game type scopes which are parallax-adjusted to 100-yds. This can occasionally cause a problem on close-in shots if I don't make a conscious effort to mount my gun so as to look directly through the center of the scope. However, as long as a do my part, it appears that the 50-yd zero is okay.
