I am posting to try to obtain more knowledge regarding the quality of metallurgy of the past vs the present.

Is there any concern shooting a Brit classic with full loads with its older steels? Is there a danger of fatigue and other issues secondary to pressures? I am not refering to using monolithic metals in older Doubles which possibly ruin the barrels/soldering 2nd to obturation.They are bad on any Double.

Would not the quality of todays metals allow for lighter Doubles with similar or better strength? ?Can a better mousetrap be built with todays steels??

Can I make a better, lighter stronger Double that will stand more pressure than the older guns and be just as reliable/accurate?? Granted the internals will not have the mechanism precision of classic Brit rifles but outstanding accuracy should be possible for the construction of medium class Doubles.Big Doubles could be made stronger for the same weight desired.

Thanks for any and all opinions given.
