PeteM:

Were you referring to this site: http://www.weiss-trading.com/hva/hvae.htm ? The Lefaucheux was later noted as being weak but I think it gets a bad rap because the advances in powder and scattergun cartridges isn't considered when the action pretty much was the vehicle that carried the doublegun breechloader thru the period of development to, or thru, the pinfire era.

Kind Regards,
