Proper Sight Picture Using Aperture Sights - What is it?

[Trojan1994]

When using 10M Aperture Sights, how does one properly set the sights and use them? Let's assume the front sight insert is a ring as opposed to a post.

1) How do I determine how far forward or back the rear aperture sight is placed on the dovetail?

2) When looking through the sights at a 10M target what should I be seeing? I.e. front ring with equal spacing around the bullseye with the front ring centered inside the Rear Aperture with equal spacing/light around the front sights Tunnel?

Any advice is greatly appreciated.
Trying to get my feet wet at an upcoming match at my club where I have been shooting Field Target but want to try 10M with my FWB601 and would like to actually do it correctly versus just playing around! :-)

Regards,

Tony

Tony,

1) It depends on where your head contacts the stock. One way to set the position of the rearsight, known as eye relief, is with help from some one else. Start by removing the rearsight, or pushing it as far forwards as you can. Then pisk up the rifle and shoulder it, settle your head on the stock, so it is comfortable. Get your helper to fit the rearsight or slide it back, so the back of the eyepiece/iris is about 2 inches from your eye. From here try little movements until you see the foresight in the sharpest focus. If your FWB has an iris eyepiece, try adjusting this to fine tune the sight picture.

2) Pretty much yes. The foresight should be centred in the rearsight aperture. Depending upon your eye relief, the ring of light around the tunnel will be greater or smaller. The amount is a personal choice. The target should then be centred in the foresight. Keep your focus on the foresight not the target. Try to mainatin an even band of light between foresight aperture and target (allowing for the wobble as you are standing). You will need to try aiming and shooting with different size foresight elements, to find the best one for you. In general chose the largest element that is comfortable, this gives more room for the target. You mihht start with a size of about 4.2mm.

good luck

That helps dramatically! I do ahve adjustable Iris for the rear and a front unit coming arriving at end of month...For now, I can at least get started in properly setting the sights! :-)
