RE: Rainsing dents in wood stocks?
If its a real dent and not a gouge (deep scrach) it can be raised with your household iron and a wet rag. Soak a rag with water and lay it over the dent. Make sure the steam is turned off on the iron and touch it to the rag over the dent. As the dent is being raised make sure that you move the rag when it gets dry. Depending on how deep the dent is it could take just one shot or a few.
Basically all you are doing is steaming the wood to make it swell up. The wet rag forces the steam into the wood instead of letting it float away.
Like polack said it will need tp be refinished so unless you are prepared to do this leave it alone and call it a character mark.
