10m Rifle Sight elements.

[andyiow]

This might seem a bit silly but I have started shooting 10m rifle for more practice in the standers. Using the club's S200T, a bit small but it works.

My question is regarding the sight elements and the 'picture' you should see. I realise that the rear element and foresight element should be concentric circles. The problem I am finding, and some other members, there is a lot of the target white between the inside foresight element and black scoring circle.

Is there any links to allow me and others to get the rifle set up correctly. I currently spray the pelelts all over the place (2 in 5 in the black )

UK Neil makes acrylic foresight elements in sets which would allow you to find a size you are comfortable with.

Or try here, these look like Neil may make them. You would need to check which is compatible with your S200's foresight, I would think they use a generic tunnel sight so this shouldn't be an issue.

Measure the diameter of the hole in the element you are having trouble with to ensure any replacement sets are likely to prove suitable.

Alternatively seek out either an individual metal element (if you can determine which size you need), or set of such.

Metal, acrylic and adjustable options from Intershoot. Here.

Sighting and foresight elements have been discussed here and here.

The main points to bear in mind are:

a. Check Natural Point of Aim (NPA) for every shot. i.e. Get into position without looking through sights. Look through sights and confirm that aiming mark is in foresight. If it isn't put rifle down, adjust position and try again until NPA is correct.
b. When aiming all movement should be contained within the foresight ring.
c. Too large a foresight is much better than one that is too small.
d. Focus on the foresight, not the aiming mark.

Hope that this helps,

As a training aid they do make a target card which has one diagram the same size as a normal diagram and 4 more which are 2 smaller than the normal and two larger than the normal,you put a group of shots on each and by looking at the group can decide which is best suited element size for you to shoot with, I am at the range tomorrow and will try to find out the card number and name of them for you

This is the card I was talking about,one I used at a coaching session

That demonstration aid is alright for prone, but for standing the primary criterion is that all the shooter's movement during the aiming phase is contained within the foresight. An essential prerequisite is establishing a NPA centered on the target in order to accurately assess the degree of movement. The other problem when you employ a larger than normal aiming mark for standing is the tendency to focus on the target and not on the foresight.

If you want to demonstrate the effect of changing foresight aperture size on the resultant group it is best to do it with a variable foresight using the target you normally shoot at.
