As far as "fact" goes, you need to separate process and design from material.
Cast is not a material, it's a process.
Any number of different materials (and steel formulations in the context of guns here) can be cast.
Cast parts do not in & of themselves use "lesser" materials.
Cast parts are not in & of themselves "lesser" parts.
A cast part can be, with the right design & material formula, the equal of a forged part, in a specific application.
(Don't wander off on a tangent, I did NOT say identically-dimensioned parts.)
A forged part is not automatically a "better" part for a given application.
A forged part is not always & automatically either superior FOR A GIVEN APPLICATION, OR NEEDED FOR A GIVEN APPLICATION.
"A forging is a higher quality material" is NOT a fact.
A forging isn't even a "material", it's a process.
A properly designed & finished cast frame, made of quality cast steel, doesn't have to take a back seat to a forged frame.
People were whining about those absolutely inferior cast (gasp!) Rugers 40 years ago.
My inferior 1975 cast Ruger Security-Six .357 is still running strong.
My inferior cast Ruger GP .357s are stronger than my forged Smiths.
Ruger's inferior cast bolt-action rifle frames blowing up make the headlines daily. (NOT!)
My inferior 25-year-old cast Ruger International .30-06 can hang with any new forged Winchester or Remington bolt-action frame without hanging its head in shame.
I'll ask again, since I have a steel Henry .45-70, a steel Henry .44 Mag, and had a steel Henry 1860 Model here for a bit- what inferior MATERIAL is used?
Not talking about PROCESS (cast), asking about MATERIAL (steel).
