With my Handi's I usually remove the barrel from the receiver then place the barrel across a cardboard box that I have cut 2 small "v" shaped notches from on opposite ends, I place the box w/barrel on it on a table or the kitchen counter and then while still in my house I sight right through a window by looking through the barrel (bore) at a target of opportunity that happens to line up and I feel comfortable with, a neighbors front light or lawn ornament, a street light bulb, a parked cars taillight, whatever I can see well. If I have to deepen a notch with my pocket knife or a pair of scissors it's simple, if I have to pad up one end with a small piece of cardboard its equally easy. Once the "target" is CENTERED in the bore, without moving the gun, look through the scope and determine your estimated adjustments, 5 up, 7 right, whatever (remember Roudys excellent point, you adjustments will be reversed from what you see). You don't have to worry about moving the gun, I usually take the gun right off the box and make the arrangements, then return it to the box and resight through the barrel bore on the target, THEN check your scope and see if the crosshairs are on the same point, if not move them again, resight through the barrel (bore) and check the scope. It's simple, easy, cheap, and can even be done without a cardboard box, I have done it by lying the gun barrel on a towel and a stack of magazines the get the right height to line up with my intended target. I have used this method for many years and it works fine. I have done friend's guns in PA and Maine while at their kitchen tables. It's free and it works. Having the gun secured might be nice but it is unnecessary when you think about it, it takes just a few of seconds to align the barrel again after each or your series of scope adjustments...Good Luck....<><....
