The Revelation Model 400C is a variant of the Savage Model 745 which is a lightweight version of the Savage Model 720.

Yes, the shotgun operates on the Browning long recoil system where the bolt is locked to the barrel and both move to the rear locked together. When the bolt and barrel reach the back of the receiver, the bolt is unlocked from the barrel and held as the barrel moves forward under spring pressure to the original position.

When the barrel reaches the forward position, the bolt is released and moves forward under a different spring pressure, loads the new shell, and locks back into the barrel.

The malfunction you are experiencing could be caused by either a very dirty gun or rust on the magazine tube which is preventing the operating spring from moving the barrel forward after firing. Another cause could be mis-assembled friction ring and friction piece.

Disassemble the gun and thoroughly clean it and remove any rust on the magazine tube or the inside of the operating spring.

Pay particular attention to the location of the friction ring and the friction piece with its surrounding spring and replace them as they were prior to disassembly.

A schematic of the parts is at the following website. Look at parts 68, 69, 70, and 71 which are the friction ring, operating spring, friction piece and friction piece spring. http://www.gunpartscorp.com/Manufacturers/ SavageStevensSpringfieldFox-33479/Shotguns-40503/745- 41378.htm

The long recoil system should be adjusted for heavy or light loaded shells. Go to the following website and scroll down to the post by RemingtonII which explains the adjustments for heavy and light loads by moving the friction piece and the friction ring. http://www.shotgunworld.com/bbs/viewtopic.php?t=6286.

if these steps do not correct the problem, a visit to your local gunsmith is in order.
