Begining zero for rear sights

[jem102]

Working with a 6" 586. Gun is new to me so did a detailed strip and clean. Absentmindedly disassembled the rear sight without counting the clicks to bottom as to where they currently were. Windage seems to center at 27 clicks from stop. Anyone have an idea on clicks from down on the frame to center of the range? Having a hard time detecting this but seems 14 up may be correct?



Thanks in advance.

I shoot bowling pins at 8 yds with my 25-2. Elevation all the way down is dead on. Each click is a certain amount at so many yds. Use to know. But it should be easy to find out. Someone will chime in soon

How much one click adjusts bullet strike would partially depend on barrel length, velocity of bullet, which determines barrel dwell time, weight of bullet which effects recoil and finally the shooter as his strength and grip determines how much the recoil rotates the barrel up on firing.

But, I usually start off with the rear sight bottomed out and see what happens. You could bottom out the elevation screw and then keep track of the turns needed to have it come off the stud.

Everything said above, plus distance to the target. There are many, many variables. You have to shoot your gun and ammo at your distance to get it dialed in.

I always sight handguns in at 50 feet as that is my standard shooting distance.

Adjust the rear sight so it visibly looks centered. Take a few shots and adjust windage and elevation as needed. Move the rear sight blade in the direction you want to move the impact to. Make sure you are using the bullets you will normally be shooting (grain weight - important). I also suggest to sight the gun in free standing and NOT bench resting it. You will shoot to a different point of impact when benching it.

Also, bring a proper hollow ground screwdriver for the sight screw.

Thanks everyone for the replies! I will start 2-3 clicks off the bottom and see what I get.

Man, that IS a detailed strip and clean.

You can either start with the elevation bottomed out, or raised 2 full turns. I would start raised 2 turns. Whichever you start with shoot the gun on a target at your selected range and fire just one shot. From where the bullet strikes adjust the elevation 1/4 to 1/2 turn and again fire just one shot. Do this one shot at a time until the bullet strike is near where you want it and then fire 3-5 rounds for a group and make adjustments from there. Initially firing more than one shot at a time is just a waste of ammunition!

Just curious, does the elevation nut still have clicks, or did you lose the spring and plunger by dis-assembling so far? Did you dis-assemble the windage too! Did you re-stake the windage screw nut? There is never any reason to dis-assemble the rear sight except when needed for repairs! This applies to any gun with an adjustable rear sight.

I usually do that when I buy one form anyone/anywhere I am not personally familiar with. The reason I take the rear sight off is that most everyone is is real good about wiping their guns down. In fact many times too good. Its amazing the amount of brown "varnish" you scrub out of the sight cut in the frame. Before I remove it count down the clicks to bottom so I know where to bring it back to making the assumption that the gun was zeroed for a practical handgun distance. However, on this adventure I got lost...
