sounds like your either an engineer or SHOULD be an engineer! lol...i do like a heavy gun for shooting...but not carrying hunting...not sure how heavy you want to go...or what it would take to balance a rifle out...guess it would all depend on each individual rifle...i think there are target shooters that add a weight right infront of the trigger area...maybe im wrong...free hand shooting a good balanced rifle makes all the diffrence...good idea...rigging up something to play with that would require potentially ruining a good rifle would be the hard part....need a way to attach a weight where you think it should go...and play around with where the weight goes and how much it wieghs...im thinking somewhere inbetween your 2 hands...but if a rifle is BADLY weighted forward then it may need to be back further or vice versa...i can see that having a nice balanced feel to it....then when you figure it all out you can rig up a weight to make the wieght practical so its not in the way and still be functionable....either in the stock somehow..or maybe something like a bow stabalizer that screws into the stock at the right point...and has the right weight to it....idea makes sense to me.....just takes some tinkering and thinking....i used to love physics class in highschool....some of that stuff was pretty neat...i wonder if theres a way to figure out EXACTLY where and how much wieght should go where.....im betting theres a way to figure it out to equalize the center of gravity throught the legnth of the rifle.....hmmmm
