这个因枪而异了吧，而且像我前面说的，跟人也有关系．看到下面这篇文章提到，握把形状也对弹着点有影响，左轮如果只是off hand比较的话，变量太多了，左轮会在手里转动，这是所有其他枪无论是pistol还是rifle都没有的特性．下面也说要先放在rest上找到真正的弹着点，再根据人来kentucky windage．
Sighting the fixed sight revolver by Dennis L. Schrieber
One of the most common complains with the fixed sighted revolvers is that they don’t shoot to the point of aim.What happens all too often, to these firearms, is that they end up in the bottom of the safe, to be forgotten.Although so called, “Kentucky windage” is often used in the normal routine of shooting, a gun that doesn’t shoot right is no fun. So, what can be done? The first thing to do is to establish that it can produce reasonable groups and exactly where are these groups located.Generally you should start from a rest.A fancy Ransom Rest really isn’t necessary, a good pistol rest or even a few sandbags will do.We are not concerned with minimum group size, just that it does group and where.Don’t be afraid to start with an over size target or at a close distance.A three to five shot group is all that is needed.What we are looking for here is a reference point.A place to start looking for the group that we are going to shoot next.It is necessary to understand that the point of impact is going to change when we off the bench.Recoil and barrel harmonics are different when shooting free hand then they are when shooting from the bags.The Colt Single Action Army and its clones are a real good example of this.They will almost always shoot higher from the hand, than from the bench.This is because the “plow handle” grips allow the barrel to flip up very early in the recoil cycle. Now, go ahead and shoot another group the way you intend to use the firearm.Using what you learned from the group shot from the bench, establish a center point for the new group.This is the point that we will move on target. Remembering the old rule for adjusting sights. “Always move the rear sight in the direction that you want to move the shots.”Remembering also, that the rear sights are fixed, we have only the front sight to adjust.The front sight responds just the opposite of the rear sight.To move the shoots up, we lower the front sight and so forth.
