Am I thinking rightly?

By contrast the Remington 700 is machined from billet? But the billet was hammer forged? To straighten the grain???


Model 700 actions are NOT machined from billets, but are made from heavy wall CM tubing.That is why there is sometimes anomalies in their dimensions. It is a major cost saving in labor as compared using billets.

Ruger is machining a lot more stuff now than they used too. 5 axis CNC machines have become more common place and it makes sense to machine rather than to cast.

As far as casting being strong or not, consider the turbine vanes for a jet engine. They are cast from single grain super alloys. Nothing else will hold up.
