In 1970, well-known shooter Derek Partridge wrote in Gun World (http://fowlershotgunning.com/up-tight-overchoking/) : “English barrel-chokers found that a barrel totally devoid of choke produces uncontrolled and widely varying patterns.” Another  example of warnings about cylinder chokes, this...

Dannymac, you were advised to switch to "skeet and cylinder."  That sounds easy and straightforward enough. There are likely myriad degrees of "skeet" choking but they are all pretty open I'd guess and all types of "cylinder" should so much the same as to be interchangeable, right? After all...

Are things like this settled by votes? Jezek

Some success, Wonko. I think, based on our videos,  many have turned their backs on "target break reading for information about where the pellets that missed the target were centered," or "TBR."  The strongest resistance comes, unfortunately, from people who teach others to shoot, both for...

Deleted in favor of re-thinking.

Earlier in this thread I wrote "I have conflicting evidence regarding a single example, that being Beretta Mobilchoke guns. If the weather cooperates, I hope to have something for readers here before ice completely takes over in Minnesota." and I just barely made it; winter's here, way too soon...

Member jwpzx9r, in a post above, was likely referring to a test I did on Briley Helix chokes. The original, liked below, shows me that he has a remarkable memory, not just for the details of the test, but also for what testing can do in contrast to what looking at patterns can (not) do...

I view of my testing results http://www.claytargettesting.com/Bore_Diameter/Bore_Diameter.pdf ...and the total lack of any testing at all by either the manufacturers or the so-call "gun testers" in the shotgun magazines (including the UK one I subscribe to for its strange but...

Readers here who liked the report of patterning tests of bore-diameters might be interested in other publications on my website: http://www.claytargettesting.com The final link on the left to the home page, "VIDEOS," needs some explanation. It is very widely believed in the US that the cause...

Wonko, the ATA rule which sets the size criterion of permitted arms as chamber-size rather than bore-size is a consequence of the arrival (drum-roll and gasps) of the Baker Big Bore with its 0.800" diameter barrel. Gob-struck reviewers opined that it would completely take over ATA shooting what...

schmokinn, I got my bore diameter information from a 2016 interview at the Shot Show of Mauro Perazzi by a German website on a popular video site. That aspect of the High Tech is mentioned at 1:40 and covered in more detail at 2:50 and following. Mauro says the bore diameter is 18.6 mm...

The only difference between the Hi-Tech bores and previous guns like MX-8 and so on is that the bores are 0.732" and not the one-time standard with them, 0.740' (or so). This provides, according to an interview I saw, the unlikely combination of reduced recoil and increased penetration.  Neil

Running any kind of "objective test" of choke tubes with the hope of a  positive financial outcome is out of the question. You would need a lot of data, access to Dr. Jones' pattern-reading program "Shotgun insight" which is, at least for now, unavailable, and a lot of time on your hands and...

I'd never found a gun with a lengthened forcing cone to be measurably superior to similar, unmodified ones: So I did the required test. I counted the pellets in 10 patterns shot at 40 yards, took the gun to a shoot to have the forcing cone lengthened and polished, and retested it with shells...
