Would anyone know who makes the largeast falling block action i can buy to make a 4 bore or 8 bore on?

State Arms Gun Company made a falling block 50 BMG rifle and I believe at one time Klaus made an action big enough for the 20mm case. Unfortunately Klaus Horstkamp founder/owner passed away in a car crash. He was a good guy who helped out the 50 cal community a lot. I do not know if the fellow who took over the company is making these actions or not, but it would be worth a call. The web site is: http://www.statearms.com/
If you find a good source let us know.

Giles whittome in england makes 2, 4, and 8 bore rifles on his Henery Harpoon action, which is a falling block.

Butch Searcy is making a falling block apparantly big enough for even a .50 BMG.-Rob

Rob, what are these giant falling block actions of Searcy's worth roughly ??

PC- I don't know just yet. Butch has promised to let me try one of his first actions. I'll let you know when I get it. Butch is in Boron Ca. which is on my way to Las Vegas to visit my best friend. I drop in on Butch whenever I'm out that way.-Rob

My best mate and I really want to step up to a .700 caliber of some sort be it the .50 BMG improved or a .700 Nitro. I am a bit partial to the .700 nitro for nostalagia reasons, and the ballistics for the .700 nitro in a bolt gun are a little better aren't they Rob ??

A big falling block may be the answer ??.

PC- Give me a phone call.I have more info for you on the .700.-Rob

BIG AL Williams

Century Arms in Australia made some very large falling block actions and made some 600 Nitro
and at least one 4 bore rifle / shotgun (see a picture of it on http://www.capeoutfitters.com/Firearms/double_rifles.htm)

Some of the guns / actions are still floating around / for sale but I haven't seen any for the last 9 months.

500 Nitro

Correction to previous post

The 4 bore rifle / shotgun as shown on Cape Outfitters is a break open Single Shot.
