One more comment.
I can understand the use /need for a light rifle but with a light rifle you give up some of the range
and increase the recoil.
If you build a light rifle in a 300 or 338 you will probably have to install a muzzle break and limit
shots to 3 or 400 yards . or go with a less powerful cartridge and give up long shots all together.
Where I hunt 700 to 900yard shots are the norm and a heavy 338 with 250+ grain bullets is
a must to knock him down where he stands.
Rather than tear down a Sendero to lighten it I would look for a short action synthetic stock,
with a #2 or #3 barrel with a break in something like a 7 WSM or 300 WSM
or even the
Just my opinion
