holland - can you really damn a "marque" because of the peccadillos of one rifle? Actually, the worst case of doubling I've come across was a Westley Richards .500 Nitro that had a nasty habit of metamorphosing into a .1000 Nitro occasionally. Admittedly, it was a "One Trigger" model, and they do have a reputation for giving problems when worn.

Nobody could fix it, not even the makers, and the owner eventually has it converted back to two triggers.
