Re: Building a Mod 70 Accurate Hunting Rifle
You really need to talk to your smith and discuss a couple options with your action.
To the lands depends solely on the reamer used and how much freebore it cuts and has nothing to do with long or short actions.
the reamer can be ordered to fit a certain bullet and seating depth. Dave Kiff at Pacific Tool and guage does this all the time with his reamers.
Look at the extended mag boxes available for the M70 such as Wyatts and see which one will give you the longest box for what I assume is a short action M70.
That will tell you what your max COAL will be for your gun, not out of the book factory specs.
Then decide on what weight bullets, load up a dummy cartridge for each type/brand bullet that is loaded to the ogive and measure the COAL. that will tell you which combo can fit in the mag and touch the lands.
Kiff can build your reamer to fit a certain bullet and seating depth for your COAL.
Now if you are taking an off the shelf gun, you simply work backwards from its max COAL after you put the longest box in it. Measure where you lands are and that will tell you what bullets will fit in your existing setup, be close to the lands and still fit in the mag.
There is a growing knowledge that many times bullets shoot much better jumped much further (as far as .120 off the lands) than we originally thought. Berger has published some info on this and many of the Barnes are made to shoot well of the lands.
As for the stocks, too many good stocks to take a "tupperware one" IMO. You want a stock that allows a good pillar bedding and is solid in the action area and no flex in the foreend.
