Let me ask this simple question. why is a fixed pin more forgiving when it comes to judging yardage than a movable pin? this is what i have found out this year when i moved back to the open class. ok, lets say i am using a movable pin and im at a 3d shoot at a target thats 43 yds and i judge it for 40 yds, then i shoot and its a low 10 or possibly even a 8. ok now, lets say im using my spott hogg fixed pin sight and i come to this same 43 yard target and my pins are set 20,30,40,50,and 60 yds and i use my 40yd pin. 9 times out of 10 if i use the 40 yard pin it will still be there.
