Theoben Rapid more accurate when single loaded?

[j rayner]

Been having a spot of bother whith my rapid 177 fac.it will group lead on lead for about half the mag but throws off the other half at random.is it easy to adjust the tension on the mags.i dont wont the old loosen a screw and springs go all over the place sindroam.anny more tips to solve this problem apreciated.JEZ

There's only one spring inside Jezer. First off to check that it has no more pretension than one turn for a starter. If you are still getting flyers, the back of the mag can be drilled to provide more anchor points and lower spring tension. You will probably need a bit of tension otherwise the inner rotor may not go back to zero as there can be tension applied from the perspex cover. I can do some snaps tomorrow night if required.
I take it you are talking about the 17shot mag rather than the 7 shot version.
ps I would expect it to group better on the second half of the mag if its a tension issue.

Thanks for that stillair1.it is the 17 shot mag.the fliers occure at anny point of the zeroing.kev g gave me some tips and the groups did get better.i thought i had craked it but i am still getting the odd one 3/4inch flyer.i think there may be some lead been scraped off the pellet either as it leaves the mag into the breech or as it enters the breech ie from the porting.some pics will be great if you can on how to adjust the mag.getting sik of stripping the gun down to no avail.to me an inacurate gun is as good as a chocolate fireguard.ATB JEZ

The internal wheel that holds the pellets does not align properly with the exit hole on the back of 2 of my mags and regardless of any spring tension adjustment i make ruins the acuracy although it is not every shot in the mag that this happens on.

I have one good mag though

Eddit, You guys might want to check this on yours (each and every pellet per mag)
