Re: Bedding a 700 LSS laminated stock?
I have a Tikka M695 wood stocked 25-06 - I have talked to Kirby Allen about getting it bedded (sorry I haven't got it to you yet 50 driver!) and have talked to a LOT of gunsmiths and BR friends of mine - the consensus is that the stock should be pillared and then skim bedded over the pillars to get the action tight in the inlet, IF it isn't a shooter already. I have heard of rifles that are not bedded that shoot well, and rifles that are purposely not bedded at the receiver (i.e. rifles with barrel blocks) but you aren't looking at this application.
Regarding your second question, you probably already know this, but to review - in my research, the critical things in a wood stock are forend flex and the barrel channel width at the top of the barrel channel - i.e flex as in you removed too much wood and the forend moves when rested on something - usually touching the barrel, and the width issue is the flat space on either side of the barrel at the barrel channel - I have seen a Sako with a larger barrel where the sides of the barrel channel had narrowed to a line instead of a flat plane, no bueno. The lamination should give you some better strength than the regular wood, I would surmise, but this is a call for an experienced gunsmith that does this kind of work! I do know that the LSS is a bigger stock, so that's good new!
I would do a Search function on the forums for LSS +barrel. Not really answering yours questions, but some info to think about if not already known.
