Dugaboy & Curl--

After a bit of research I will plead Mea Culpa and confess to being a total dunderhead.There is no need for any other redundant Double to substitue for the present 450/400 rifles unless factory ammo is manufactored and the 408 guys start blowing themselves up.The 450/400 is great as is.

As Dugaboy has so kindly,plainly and patiently stated, the 450/400 is clearly presently only a HANDLOADED CARTRIDGE and thus the responsibility of the handloader,NOT the riflemaker.Every Double manufacturors could change over today and make only 450/400's from now on with NO LIABLITY.The real rub arises in that no major gun manufacturor would do this without having a source of factory ammo for the "new" rifle and then the 411 blowing 408 rifles scenario rears its ugly head.

The Double rifle faction is probably small enough and motivated enough that the 450/400 could survive and prosper without factory ammo.

Ask folks if they would buy a 450/400 even if they had to handload and I bet they would say YES!! I would!!
