First - I've never done a bedding job. I've never really thought I needed it, but I do want my groups to be tighter.

I have the model 12 LRP in .260 - very heavy barrel, precision trigger, HSPrecision stock, CDI bottom metal. How necessary / beneficial is bedding for this action/stock? The aluminum bedding in this stock looks just as solid as the aluminum chassis on my 308 - does that mean I don't really need to bed either one, or does it mean I should really bed both of them? Would a barrel swap have any adverse effect on the bedding job?

Thanks!
