ocabj & jimmyc75:
I recently "bored out" my factory Birch stock, & fitted my GM 18".
I used a full sheet of 60 grit, wrapped around a 3/4" dowell - then moved to a 1" dowell. I alternated between these two dowells & test fit several times, before I was satisfied. Even then I was having some doubts, so after I painted my stock, I ran the dowells through again. After another coat of paint & two coats of satin polyerethane, the fit was great.
I used a medium thickness piece of metal, (same thickness as a heavy washer) cut to fit down inside the stock & drilled a hole in it to allow the take down screw to pass threw. I stippled it (roughed it up - small indentions) so it would grip into the wood. I now have a floating barrel, with a pressure point pad 1.5" from the end of the stock.
I'm satsified, for the time being... I was able to get out, before it started to snow (again!) & zero in my scope... 10 shot 1" groups @ 50 yards. I'm sure it shots better than I'm able to make it shoot.
Sorry I'm rambling on... It's my first attempt, & I had fun doing it!
