Thanks Mete,
Part of my problem is deciding whether I should have this fixed by Browning under warranty - I did once and it didn't work. The rifle was glass bedded at the factory, and the forearm was cut at the factory such that the barrel should have free-floated, but didn't. The correction the local gunsmith provided (under warranty) kind of worked, but only temporarily. If no amount of repair will fix this problem, Browning may have to replace the stock. Right?
If the answer to the above is no (i.e. even if fixed, will still warp), then I will probably look at having the gun professionally bedded.
Moreover, if the quality of fix provided so far under of warranty is any indication of future repair, I'm not certain I want this fixed under warranty again.
