Whether a part is cast or forged is but one aspect in the strength of the part. The alloy that is used, how the alloy is heat treated, the physical dimensions of the part and work hardening all affect the strength of the part. Some alloys are so tough and some parts so complex in shape that casting is really the only practical way to make the parts.
That is true. For years I have read about stretched frames in S&W's. I have never seen it because they are strong. I have owned many of them. But I still have my cast Ruger SBH with well over 81,000 heavy loads through it and uncounted light loads. There is no measurable wear. BFR's are cast by the Ruger Pine Tree foundry and freedoms are cast.
Forging is expensive with no advantage over new steels. It makes cheaper steels stronger is all.
How is the "X" frame made? Had a few here and they sure look like castings. Done right with the lost wax process and good steel, cast is stronger. You would be a fool to shoot Ruger loads from a S&W.
