Opening Chokes

[esetter - Gerry Addison]

To anyone that has opened the chokes on your Repro barrels. Question since they are chrome lined did this present any problems when they were opened up, reamed? I've had a number of barrels opened up, but none with chrome lined barrels.

Gerry - I had my 28 Ga Opened by Briley. No Problems - you might want to call them. Billy

Thanks Billy, that helps.

I had my repro 28" 28ga chokes opened by Mike Orlen several years ago with no problems.

Great, sounds like no one has seen a problem cutting into the Chrome lining.

In these days of non-corrosive primers, what advantage is there for chrome lined barrels?

Indeed!

Why do plastic shot cups influence this? Never heard that before

I've heard from modern day muzzle loader shooters who shoot saboted bullets that plastic fouling\buildup is a problem, and cleaning it is a PITA. Rifling in the barrel probably contributes to this.

Speculatively, chrome plated shotgun barrels may be smoother and\or have less of an affinity for plastic fouling? If so, opening up a choke and removing the chrome plating may create a place where plastic from shot cups could build up?

I would not let that stop me from making the chokes what I wanted them to be, but there may be an added step to remove plastic fouling after a lot of shooting. Just a theory at this point.

Plastic shot cups, which have been in use since the 60's, not only tighten patterns by virtually eliminating shot deformation - and bore scoring from the more recent steel shot - so I don't get the need for chrome lined bores either.
