Anyone have and idea if a jeffery double shotgun action is anywhere near the same as thier double rifle action. I picked up a cheap 12g hammergun and want to rebarrel it to something like 303 british.

Tonto,

It is up to you, but a 12 bore is a mighty BIG action for a 303 Brit double rifle.

Does it have a Doll's head or Greener cross bolt? This will ad to the strength of the action. If your considering this, then I might suggest buying the book on building double rifles on shotgun actions. It has a good section on selecting actions. You might look at the flats for proof information. Make sure it was nitro proofed. There is a difference in the European 12ga shotguns. some were made as a light upland game gun intended for light loads. Others were a heavy 12ga inteneded for heavy loads and waterfowl. The heavy 12ga is a much stronger action.



I've put lots of rounds through my 470 on the Belgian 12ga action. I messed up one barrel while regulating and have a new one to replace it, but the action seems to be holding up fine. Mine does have the Greener cross bolt.



The pressure of the 303 might be a problem with the shotgun fireing pins. You might have to have the fireing pins bushed to reduce clearance if need be so you don't experience a pierced primer.



Just thoughts, not an expert on anything.



Expert. To understand the word it must be broken down in to it's sub words.

spurt- a drip under pressure.

I know 12 gauge is large for the 303 but its an older hammer gun and I was hoping to keep the pressure down. I have that book lars its a great referance hope I can make something out of the action.
