 My stepson (Rico) has a model 24 field grade series s. Mine is a field grade series p. When cleaning his barrels of plastic fouling I noticed helical grooves in the shotgun barrel. These grooves are far too fast to be rifling (like a 1 in 1 twist rate). From my measurements it looks like full choke. It shoots slugs with amazing accuracy and repeatability it appears that someone regulated the barrels and replaced the band with a soldered block. Also his trigger breaks at 3#. Obviously someone did some custom work to this gun. My question is "What is that groove, how did it get there, and why? Has anyone seen this before? |

Are the grooves deep enough to feel with a finger or a right angle pick?

Maybe a chip got caught in the reamer when the barrel was being made, and it slipped through QC? If the twist was slower, you might have a paradox rifle! Lol.  |
