One thing that some of you might be missing is that the synthetic thumbhole stock is has completely different forearm construction than the wood laminate or the regular synthetic.
The thumbhole does not have a
barrel bed along the forearm of the stock - for the lack of a better words. The only bed is right at the front of the forearm where it is point bedded.
In the case of
statjunk's stock the shim(s) will allow him to relieve some of this "upward" push (and I really think it is an excessive amount of push)the point bed is applying to the barrel. (And also please remember, he and certainly I really do not know WHAT the problem is yet) I do not think he plans on leaving the shims in certainly not two shims per pocket - but it will allow him to see if the barreled action will shoot better with a free barrel. If all of this works for him them he can begin the repair of the stock. If it doesn't work - as it might really be a barreld action issue - he can still send everything back to TC and not have voided any part of his lifetime warranty.
Gosh i hate writing some thing like this - I hated English classes - this whole thing probably only makes sense to me.
What I have tried to help him with is to
FIND the problem safely then work on curing the problem/
