View Full Version : Choke tubes?

I have a couple of guns that have interchangeable choke tubes but…… being old and set in my ways I have always preferred the ones built into the barrel. Those are getting more expensive and harder to find.
How good are the interchangeable choke tubes?

If they fit properly, are used with a good anti-seize lube, are removed after every shooting session for cleaning and inspection...they are pretty good. I prefer to use the extended tubes when using steel shot, so that any damage to the tube is external to the barrel, and you can get rifled tubes for use with slugs to turn a general purpose barrel into a slug gun...did that with my Remington 870 with a clamp-to-the-action scope mount for Bambi hunting. They can be damaged by overtightening or allowing them to vibrate loose. Either case can allow a shot charge to catch on the edge of the tube and possibly damage the tube or the barrel. Remington did have a problem a few years back with recesses misaligned to the bore that left the edge of the tube in the way of the shot charge. Not a pretty picture when the barrel bulges or bursts at that point! My understanding from a now-retired informant at the factory is that they did not use piloted tooling for the recess and threads.
"How good are the interchangeable choke tubes?" - pretty damed good! The real advantage is flexibility. Most people use too much choke. With modern loads, everything shoots tight.
I'm not disputing anything David said, but problems are few & far between. Just keep the tubes lubed & snug. Anti-seize is probably overkill, but making tube removal and lubing part of your cleaning procedure is a good idea.
Mis-aligned barrel threads may have been common hrs ago, but very uncommon. In good quality guns, it's not a problem. After all, these are shotguns, not bench rest rifles. JMHO.
