The fit of the forend at the receiver end is untouched and absolutely perfect. I did ream out the rear sight base, and fit it, but I was careful to use the knox flat as the datum. As it was for breeching up. The problem I found would explain the problem of the rifle shooting some 600mm out to the right at 100m, and the ordinary groups. I just hope to find that the action taken has cured it!
I've got the last edition of Jim Sweet's book but the later ones had info about No4 bedding and Omark bedding. Will try to hunt down an earlier edition.
BTW Bruce_in_Oz where do/how have you come by the wealth of information you possess on these things?
