Anybody have a way to precisely move a rear sight a measurable distance in it's dovetail? I know I need to move it .019 and don't want to just endlessly tap and try.
Thanks

Use a c-clamp?

You can mark the sight and barrel to get some idea on how much you moved it, but it will still be a guess. Tapping is the only way I know and it usually takes a few tries. It's not precise like moving a scope, but I always seem to get it in a couple of taps.

Measure the placement of the rear sight in the dovetail with the depth gage part of a pair of dial calipers. Tap and measure, repeat until it moves .019.

Providing .019 will center the shot.

Turtle,

How do you know you need to move the rear sight .019", which is a very precise amount.
Just curious!

That's about half an inch at 25 yards if the sights are 3 feet apart.

Using "similar triangles" from High School geometry. Saves a ton of time getting a rifle sighted in.....especially in filing down a front sight. Best wishes, Marc

tapping and shooting, tapping and shooting is a whole lot more fun than tapping and measuring.

Wow, some times, we waaaaaaay over think things.
You're about 4 or 5 shots away from getting it done. Seems like in the time it took to write this, your gun could be sighted in.
Tap it, and shoot a couple.

Different strokes for different folks. I'm tempted to do some measuring next time I sight in a new rifle. Unless I get lucky the first try!

Turtle · « **Reply #11 on:** July 05, 2017, 08:03:27 PM »

I use the formula for sight correction I found in a magazine years ago. It is amazingly accurate-I no longer shoot to recheck zero as it is always right if done properly. . For elevation I measure the front sight height with calipers and file till it's right. Windage adjustment has always been a more of trial and error. What I did this time is to clamp 2 1/8" thick metal pieces to the barrel on each side of the rear sight, measured to the side of the sight, and drifted it till it showed .019 movement. I still would like to find a better system than the metal pieces. All this was done on my bench at home where it's easier to be precise.

Did it shoot dead center after your adjustment? (Windage)

I had a 40 year career in Manfacturing Aircraft fixtures and components so measuring anything just comes natural. A good set of Dial Calipers is one of my most important tools. I always try to be as precise as possible, it's the way I was trained. Others trained in different methods feel comfortable in their ways.

You guys just bored a four inch hole in the bottom of the fun barge. I enjoy shooting, so I shoot a little, tap a little, maybe tap her back a little, shoot some more. If I was going to do it your way I'd trade my gun off for a calculator, and a micrometer.
I spent a large portion of my working life specing industrial bearings for geothermal steam wells, and large scale mining operations. So the chances of finding working tools in my shooting bag with my playing tools, are pretty slim.

Yes, it's dead on now. I shot it again just so I could report that, but as I said, It's always right on if done right. I would rather spend my time and powder/lead shooting a properly sighted gun than group/tap/group/tap----. Different strokes.

Turtle, you said that well.

Sharpsman · « **Reply #18 on:** July 06, 2017, 05:59:53 PM »

I shoot, tap, and file! Sixth shot is about where I want it...with a slight breeze from the 3 o/clock side! I'll shoot again and recheck after the rains subside!

Shooting is shooting whether you're walking in the sights, or shooting a group in the bull. They both need accurate shooting.

Gosh, after 55+ years of shooting and tapping I find out that my rifles have been improperly sighted in.

How's THAT? Isn't tapping and shooting the RIGHT method? I suppose there are more technical ways of doing it, like by figuring sight radius, range, barrel whip, resting method, atmospheric pressure, sun angle, etc, however after tapping and shooting, I find THAT is a terrifically simple and quick way of sighting.

Reading a few posts and writing a short one, constitutes about the same amount of time it takes to sight in a rifle that starts with even heights of front and rear, set in the middle of the flats.

I should qualify that with, of course, I don't have to wipe between shots.

smylee grouch · « **Reply #23 on:** July 07, 2017, 12:48:05 AM »

Yes Daryl I think that tap and shoot is the right way for me anyway. I was Trying to point out that is how I have done it for a long time. In another post it seemed to be wrong and the measure, tap was the proper way to regulate your sights.
