Thread: Add weight to synthetic stock

I'm wanting to add some weight to my rifle stock, easiest way would be to fill it up with lead shot, but I don't have any of that sitting around, and looks like you can only buy it in 10kg bags.
Fishing sinkers or dive weights is another thought, but not sure if they will actually fit (and I dont have anything on hand to try).

Has anyone done similar and have any ideas I can try?

No idea how much weight it's possible to add in the butt cavity, but any weight added will help it sit on on a rear bag and bipod better.
