I've been chatting lately with Chapuis about all things .450/400 NE 3".

Yesterday they pinged me to say their supply of ammunition for barrel regulation has become so uncertain they've stopped taking orders for that cartridge.

I've no doubt it's the same situation for the other European builders of double rifles.

I may still go ahead and search out one that's already here from across the pond as I almost have a life time supply of components. Just need to bulk up on DGX Bonded.

I'll likely know by EOM.

It's you and the bullet, and all the rest is secondary.
