HELP

My rifle a BSA Supersport (.177) is playing up!

I zeroed a little while back at 10m to get a grouping, which I promptly got.

In the last two days I have moved back to 25m and have been trying to get a group before adjusting the turrets to zero it, this is proving impossible. I get a few pellets to land in one place then the zero moves and I get a few more pellets in that spot before it moves again etc.

Any ideas to what may be causing this?

My rifle is in almost good as new condition (bar the odd scratch <img src="http://jsramsbottom.co.uk/bbs/e/icon_frown.gif" alt="Frown" width="15" height="15"><!--graemlin::(--> ), the scope is attached tightly and is not moving, and the bi-pod did not effect it at close ranges.

Even if i had knocked the scope I would still expect it to group.

In case it was the bi-pod I have tried in all other positions (standing sitting and knelling) and still have the same problem.

It is not me as my mate who also shoots tried and had the same problem.

My rifle is a little over 3 1/2 years old and has never done this before.

Please help

Check the stock fixing screws Matt.

Definitely check the stock screws, they have a habbit of working lose on Supersports. Check also that the barrel isn't noticably wobbly (it happened on a Meteor of mine).

as above, check the barrel for looseness and the linkage......but, and I am not teaching you to suck eggs here.......has this gun been dry fired recently? You might find your spring has broken or your piston has been damaged. I know, because the symptoms were the same as one of my meteors a few years ago and it turned out to be a broken spring.
best I can offer mate.
