[98s1lightning]

Who's the go to gunsmith to lengthen a SA Ruger M77 tang safety rifle mag box from standard 2.800" to 3.100"

Or maybe the process is simple enough for the home shop machinist

I'm not sure if barrel throat needs to be modified as well?

Ability to shoot a variety of heavier bullets for caliber, and maintain velocity.

I've loaded for a short action Browning A bolt and have had very limited options for bullets at 2.800" in heavy for caliber.
