TargetTalk

I moved my front sight on my Steyr LP10 from long to short position. I could not settle my mind on short radius or long radius. But when I move my front sight back and forth, I noticed my elevation seems to change. But some times it doesn't seem to change.

Should changing my front sight radius change my target hit elevation?

Yes it should.

Hmmmm.

I initially thought so too.

Then I thought about it some more . . .

As long as the surface upon which you are moving the sight is parallel to the centerline of the bore, the sight line will maintain the same angle to the bore centerline.

So no, for a high-quality match grade arm, you shouldn't be able to notice any elevation change . . .

. . . of course, this assumes you are aligning the sights "neutrally" (e.g. you don't have any human bias in yoiur sight process) in the first place.

The key is the angle between the sight line and the bore line. As long as those are constant, the poi should be constant.

What am I missing?

Aha!

Sorry bout that.

When the gun is tilted muzzle up, moving the front sight forward and back *will* "raise" and "lower" the height of the front sight above/below the boreline.

To quote the great 20th century north american philosopher (Homer*):

"D'OH!"

*simpson, that is

While practicing at 50m with my free pistol I moved my front sight to the closest position possible from the farthest position. My group was noticably higher.

In FITA archery it is generally accepted that having your sight out as far as possible gives you better accuracy. Having your sight closer to you gives you the appearance of greater stability during the shot process.

Being an old archer I brought my free pistol sight in to try it. That is when I noticed my groups were higher. I did not notice any increase in my being able to hold sight alignment any better (or worse).

Come see us in the woods.
