Help needed about prone position shootin(50mtr)!!!!

[raj]

I practice 50mtr prone position shooting with my IOF .22lr Rifle.
Even after taking good care about sighting ,i have a tendency to shoot upwards(12 'o clock).Left to right shifts are almost nill as i do practice much with air-rifles, but even if my rifle is zeroed properly,my shots land up on the 12'o clock line above the bull.
I experience same problem with my air rifles too.I also tried shooting a little below the bull to compensate for error,but cant determine the exact amount of compensation needed.
I need help about what should i do??
Do my rifles need any adjustment ??please help.

Hello raj
Is the front sight you are using the ond that came with it? Do you get grouping @ 12 clock. ?do you use blinder? I think it is your breathing that is causing the problem

Hi raj,
If it is the stock model without any mods then,
There are two flaps on the rear sight, Try to shoot 10 shots with each flap and note the diffr, Choose the flap whichever gives you the best grouping. Other wise You will have to do filling(removing) on the top side of the rear sight Flap. Do it very slowly and cautiously and try again.
Thanks.
All the best...

You are just letting your front side image land a little higher on the rear one .
Level it in such a way that from the bridge of your rear sight you have only enough of fore sight visible as to touch the imaginary line over the bridge.
This will hit it right at the spot , does in my case. cheers

Sir,my rifle just have one flap at the rear-sight which is more like a rectangle than a 'U' shape.

Sir, the front sight is the same one but i have filed it down and its narrow now.yup i get a verticle group from bull to #6 ring all on the 12 '0 clock line. i dont use blinder.

Use blinder on your left eye. This will reduce your strain to keep one eye close. Our eyes are set to work together so our body will try to open it .the shots are moving up and down because you are not getting same level of half breath

...I think it is your breathing that is causing the problem...

Cherian may be abs right, since you seem to be having this problem in both Prone and in Air Rifle.

However, check out the below image and let me know what kind of grouping you get (A or B or C or D). It will help in analyzing the problem better.


There are several aspects that induce inconsistency in grouping including:
1. Change of gun position
2. Inconsistent aiming
3. Inconsistency in Trigger function
4. Inconsistent breathing technique
5. Inconsistent follow thru
6. Ammo make/batch not matching the barrel causing double groups.
7. A rear sight that has a play
8. Inconsistent sighting picture. This can happen is the fore sight is not completely matt colored, and/or if it shine much
9. Inconsistent 'vision-of-aim' while firing - This depends on where your focus is, while you have judged and decided to pull the trigger... and after.
10. Inconsistent stance - can happen even with stance changing while you load or bend to see the scope, etc.

Also, it would be helpful if you describe your general build. Once we get to the more 'probable' reason of the problem, I will suggest some remedies which you can try and get this debugged

i will try to get a blinder.any idea where i can find it???


Hi Mr TenX ,
Thank you for your detailed reply.

My grouping is like B & D.its more like D if we remove all the shots below the bull.
About my build:i am 6ft,74kgs.atheletic build with more mass on my upper body than lower.i do regular weight training.
do you think a hard trigger can result in this error??

[raj]

here is a target paper.10 shots at 15mtrs with my air rifle,same vertical drift.

[TenX]

OK.. Got it.. I am framing a long reply for you... will keep updating it thru the day...

...do you think a hard trigger can result in this error??

Very possible. The pressure that the fore finger exerts on the trigger, if at the wrong angle, can and will move the shot. By wrong angle, I mean pulling the trigger in any line other than that of the rifle itself, towards the butt.
However, you most probable mistake is one of the following. Try to rectify that in this order, and see if it works. Dont combine all the remedies in one go. It may seem more than brief, but is well worth, considering these as the basics of good shooting. I would also suggest that you dont see thru the scope afterevery shot. Try the variation and check your target after 5 shots. This will give you a proper grouping assessment.

(Removed part of the post since I have duplicated it along with the other tips further this discussion)

Thank you Mr. TenX,
i will follow your step #1 and tell you the results.waiting for the remaining tips.

Raj... Please bear with me for this weekend, as I am terribly pre-occupied. Although I did want to finish the post today, I guess I will only be able to do this on monday...

[sawbones]

Maybe its just my eyesight but I did not catch on what hold you are using 12 , 6 , or aiming area to get a group in target shooting you have to shoot at a vision not a target at 50 yards you cannot see the bull so it is a consistent picture that you shoot at and as the guru says you will be surprised by hitting the 10

Anyway whatever you are doing is not consistent which is why the group is wandering

another thing I would ask is wether the beginning of the string is better or the latter part or is the pattern random

anyway keep at it you will find YOUR bull

[TenX]

Pretty right there Sawbones... I planned to cover that in the next part (2. Aiming - target sighting )

[eternalme]

I have a quick question for Amit - Do you have your airguns also tweaked with the filing you mentioned earlier ?
Based on your 12'o grouping I am assuming that the front sight is playing a role in the vertical raise in your groups.

If you haven't played with the front sight of the aiurguns then try the following.

1: Align fore sight and rear sight in such a manner that the tip of the front sight is touching the imaginary line drawn over the shoulders of the rear sight.
Breath in half lung capacity , hold, align the sight combination to the bull in such a way that a little of it is visible on the top of the sight image, and remember this point and image hence formed, ie, the rear sight and front sight alignment and the bull position in relation to these.
Squeeze the trigger, let the breath go in while still holding your eyes and cheek contact still and follow through.
Repeat five shots in the same way, don't pay much attention where it has hit, don't make any alternation to the sight image and bull positioning in relation it.

After you have had five consecutive shots, post the image of grouping hence formed.

If you still get grouping at 12 o'clock position higher then you need to align the sight at the bottom of the bull making the image appear with bull resting on top of the sight combination.

All the best.
