Semi, the Mod 70 is probably pressure bedded like a 700BDL SS is. They put like 7lbs of upward pressure on the forearm of the stock. Sometimes this works, but most of the time they do it so poorly, that it may hinder your performance. Melvin Forbes, from NULA pressure beds his guns, but it is done with great care and uniformity, where it helps lower down the vibrations when a shot is fired. How does it shoot? If its not acceptable with various ammo, I would look forward and take it to a gunsmith to have pillar bedded, and barrel free floated. You usually want a trigger job at that point too. Bad thing is probably set you back 150+.

As standard operation, with a 700BDL SS, I would take to the gunsmith and have the work done. I have always seen it help performance greatly. Only one instance can I remember that pressure point at the end of the forarm helping me.

Another option is a stock like an H-S precision with aluminum blocks already installed. It will raise the wieght a tad however.
