Thread: Browning ABolt 2 - emptying sand from stock?

Got an old A Bolt 308, still doing the job well enough but have wondered about emptying out what I presume is sand you can hear moving round in the plastic stock and replacing it with expanding foam to loose a bit of weight. Gun is pretty well suppressed and is fairly well balanced at the moment but on the last big carry out was mulling over all options to loose some weight. Anyone else done this or am I risking ending up in the 'what have you done Bubba' thread?
