Even if the shot is soft enough, there's still the pressure issue. Steel can't be used in "vintage" guns like the Browning Superposed. But the Browning Superposed will certainly shoot SAAMI-pressure lead loads that should not be used in other vintage Brit/European (or even American) guns. So I think--until the pressure issue is resolved--that "vintage gun" may not mean the same thing to Remington that it means to us.
