Built a few of them. He had a great reloading manual, lot of interesting stuff in there. Met Art when his facility was in Indiana, stopped in when i was doing the hillbilly tour. Quite a colorful character. - dan

Built on Enfield actions, lots of gunsmithing required to sporterize them!

Interesting the write up about how it takes gas... firing a .375 in a .416 with no damage to the rifle. I would expect that of any rifle because of a considerably smaller bullet than bore.
I wonder how it would handle firing a .303 British in a 7mm Rem Mag. I know of a Remington 700 that survived that with no damage. The bullet exited the barrel, the superior extractor system sealed the breech, the bullet swaged down to 7mm within it's length and exited the barrel.

I suspect that a lot of the actions used were from Indian drill rifles.
