crshelton & Grenadier,
Guess you picked that I have a weakness for the different or odd calibre kind. So things like a completely different or unusual calibre in a certain rifle really gets my attention.
For a classic example being the 450 Alaskan on a 1886.

Most certainly a doable project & giving those rifles another hard hitting option & better projectiles.
In reality Woodleigh is now making all those 'unpopular' cartridges that never really made a success for themselves far better & more reliable (& safer) than originally first done.

As to having a .405 & in a 1895 - I certainly wish!
Keep up the good work!
Cheers
93x64mm
