Bigfoot,
Hmmm, Well...I have a scale that may do the trick. I have to dig it out of the shelving unit.
Now, I can weigh the resin stock, and then I can weigh the one piece barrel and action, of course if you add 'um up it should be the total weight of the gun. So, if I give you the weight of the barrel\action, and you know the weight of your total rifle, then you should be able to do your math from there. Waite...your barrel is different than mine...scratch that.
Give me a day to find the %^$#@ scale.
Dave.
