Am I thinking rightly?

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


In the case of the REmington 700 the barrel at one point was a casting and then heat treated and then hammerforged. The action is a blank of SS or CM and then heatreated, there is no forging.

Investment casting orients the grain structure in to the shape of the finished object and results in enormous strength.
