thanks for the link

they do seem to be making a .375h&h these days. I think tinker is right the new ones seem to be dolls head fasteners. On the older shotguns like the r12 or r13s that ive been looking at have what Darne calls a barrel bolt. Any idea of how strong these lockup compared to something with a greener crossbolt?

Looking at their express rifles shown on the link some of their rifles have this barrel bolt, I dont know if the dollshead is specific to a certain model or what. I can read a good but of french and it doesnt seem that they specify which models have which.

apr1775: There a quite a few listed on gunsinternational at the moment. Honestly though buying a darne shotgun for $2000 and then to still build thebloc system is not really that ideal at this time, but if i was going to do it the only reason would be just to have one. It seems 12-bore is less common than smaller bores
