I have just got hold of a 'BSA Magnum' it is is very good condition and was cheap. I thougt it worth investing a few coppers in , so have put in a new breech seal and checked it over as you would. So why is it so awful? I cannot get a group of any sort all shots are completely random. I am a reasonably competent pistol shooter and can get them all on the card with any other airpistol.

Does anyone have any history/ experience of these guns? And can anything be done to improve matters or are they really this bad?
