I agree, bill. I was only referring to the titanium chokes they sell. They say not to use anything but lead in them. I'm sure you are referring to their chokes made of steel.
I have been impressed with their quality, as regarding their chokes. I have accumulated somewhere around 23 or 24 S-1 series Briley thinwall flush choke tubes. I have never ordered a one from them, except for one order where I used two gift certificates I won at a sporting clays tourney and used to have a Perazzi MX-8 threaded and got about 8 tubes with the deal. The rest have come with guns I have bought used. Recently I got concerned that by switching the tubes between guns I might have some that were differing in I.D. and get myself into trouble. If the "lower" end of a choke tube, the end away from the muzzle, is not sized very properly to the bore diameter at that point, i.e., if the i.d. of the tube is less than the i.d. of the bore the wad can and will catch on the edge, start shaving plastic from the wad and compressing it behind the choke tube, forcing it inward until a shot charge in a wad hangs on the deformed end of the tube and blows the tube out and/or splits the barrel. I took all of them and carefully measured the i. diameters of all 23 to see if any were made for different bore diameters. They were all exactly the same diameter. They all also are large enough diameter, in relation to the bore, that as the wad enters the choke tube there is actually about a .004-.005" enlargement so that there is no possibility of the wad ever catching the edge of the choke tube as it enters it.
This is how all are supposed to be made, but many aren't, much to the dismay of shooters who have blown up their muzzle and didn't know why. Of course, letting a tube get loose and backed out a few thou can also allow this plastic to get shaved off and caused this problem, but by assuring that they are sized properly to YOUR bore, this shouldn't happen even if you inadvertently let a tube loosen a slight bit.
