Weight Loss

I have to admit it. I'm not 25, 45, nor 55 anymore. I truly love my Ruger M77 boat paddle, but it's seeming a little hefty these days. Are any of you experienced in shaving about a pound out of a brick stock ? I'm sure some judicious channeling of the forearm interior, and maybe a drilling into the grip would yield benefit, but to what lengths remaining safe?

Shortening LOP, Drilling the grip and buttstock as well as sanding and sliming the forearm and grip area, and taking material out of the barrel channel are the easiest ways and can yield a reduction of and 1lb or more depending on density. Keeping the stock integrity and not affecting the balance too much are the most major concerns.
