Re: Tacticool stock modification...... lead weights...
Drill & fill works just fine, both in the buttstock and forearm areas. Lead shot works well, bedded in your favorite compound, and it won't burn or char your stock material like molten lead will.
Adding weight for stability or to duplicate the heft/feel of another rifle are both worthy reasons to do this. If your goal is to reduce recoil, then you will be better served by trying to figure out why the recoil is disturbing your sight picture, creating physical discomfort, etc.
The derisive comments posted above are primarily due to the liklihood that someone so sensitive to recoil is likely to be a troll, and I cannot rule out that possibility, my self.
