OLD vs NEW - Folding .410 

You know what you say makes sense

We have 3" Fe #6 and #7.5 @1400 fps from Federal and Winchester in the US, ask for those. Otherwise people also reload .410 steel using 3" Fiocchi or Cheddite hulls and BPI TPS410 wads for steel.

Also I use a Mossberg 500 synthetic in 410 that uses Browning Invector pattern screw-in chokes. All sorts of choices with that, but up to #6 steel has been fine in the fixed-full of current 500s.

Thanks for your comment and they do not come into the U.K anymore we have done a test on here with them, a long time ago TSC Team

Big chance they only imported it. They did import Belgian shotguns and engrave d'Beaumont Wapens Maastricht. It was quite common for an importer to do. Like the US importers still do. Its not likely Beaumont made a folding 410, 1, 410 never been a hunting caliber in the Netherlands. 2, Beaumont specialised on making custom order (shot)guns and sales of other brands after the militairy contracts. The son in law of Eduard d'Beaumont was a Stevens from Liège, famous gun producer family, like the USA brand Stevens, wich was a branch from the same Belgian family. He probably had many contacts in Liège, he worked in the industry there. And, because the Dutch didnt have a proofing station after the Belgians seperated, Beaumont had to proof their in shop made guns in Liège. There still is a chance Beaumont did make your folding shotgun. An A grade Belgian brand, A(uguste) Francotte did make some folding rifles in single and over under (!!)410. Holland and Holland from London also made some, but not in .410 but in obsolete calibers like .300Rook&Rabbit. Pre 22 rimfire those small bore centre fires were populair with the rich (ladies). When the cartridge became obsolete many were bored out to .410. bit they still are high quality masterpieces. Your Beaumont migth even have started our in an obsolete German caliber and became a .410 Who knows, but they are pretty fun to own anyways. I have 2 Belgian black powder proofed pre 1945 folding shotguns. A single shot "piece of junk", likely was someones workhorse on the farm. Sound and solid, bit not the best looking 1. And today i got a 30" double barrel 1 in very nice condition, probably was some Belgian guys kitchen corner of next to the bed bit keep it oiled and cleaned in between killings one. Im sorry for writing the whole bible.

@pino colada Thank you for the information. I also think it is customized by beaumont and not build.

@@jeroenmunnikde7873 do you use it or have it as a nice wallhanger?

@@jeroenmunnikde7873 most often they are still in use and beaten around. Anything with the name d'Beaumont on it should be kept like you do. You said it already its a pretty rare thing.
