Hi Tom

yep it could very well be. It is only my predudice after all.

But consider this, for as long as I can remember whenever we want to get real horsepower out of an engine one of the first things that needs replacing is the cast crank with a forged item, same with the con rods.

Are Ruger castings good enough for their origional purpose. I have no doubt whatsoever that they are. But forging does realign the molecular structure of the steel and toughens the component.
When we look at conversions we are stressing the actions beyond their design limits and I just like an added margin.
BH in his article about his nice Red lable 45-70 conversion says himself that he sticks to low end loads. These then are far below NE loads.

Regards
