Accuracy problem, help please

[ledders666 6]

Im shooting a aa s200 .177. I have my gun zeroed at 30 yards. I zero it whilst sat on a picnic style bench. Shooting like this is very accurate. The problem I get is when I move on to my bipod led on the ground.

The shots then become very inconsistant and not accurate.

Would anyone be able to shed some light on this?

 

thanks

Different head position on stock/movement in bipod ?

[fraggle101 28]

Make aure the action is secure in the stock, and the bipod is secruly fitted to the stock.. make sure there is no movement between the three..

This is an exple

Wobbly bipod? Or quite possibly Paralax error caused by your eye positioning when shooting in the prone position.

 

Do you zero on the bench with a bipod?

Also, as Matley said, make sure you keep your head in the same position when taking the shots, you could be getting paralax error..

.. I havent tried the bipod on the table. On the ground its very sturd. I thought it may be a different haed position but its the inconsistancy which gets me

The bipod isnt secure to the stock its one of these http://www.jsramsbottom.com/products/bipods--rests-bipods/gtbipodabs-guntuff-abs-bipod---fits-most-break-barrel--underlevers.html would that make such a difference even on a pcp as its very sturdy when aiming?

im sure my head is in the same position i did try to move it about but it didnt help

Your point of impact will be different if you use this type of bipod pal.

 

The S200 only as a few inches of barrel sticking out after the cylinder and if you attach a bipod on the barrel you will totally change the harmonics of how the rifle discharges.

 

Even a so called recoilless rifle isn't recoilless (hammer bounce etc) hence your higher impact on the target.

 

This is magnifying a ballistic process called JUMP.

 

Also the added weight of the barrel bipod with cause the barrel to lift under its own weight from the stock and action causing your impact to be higher.

 

Barrels need to be free from harmonic obstructions, better fit a bipod to the stock pal.

Great advice thank you. I will purchase one to fit the stud. The clip on one seemed a good idea for a fiver.

 

Thanks everyone
