Lefever claimed in a 1909 Forest & Stream ad to have originated "the taper system of choke boring".
This is the description in Hunter-Trader-Trapper August 1912
Click here, then on p. 73 for the entire article
http://books.google.com/books?id=Uy...=onepage&q=Lefever%20gun&f=false

[Linked Image from photos.smugmug.com]

An occasional Lefever 12 gauge has bores tapering from the breech to the muzzle (.756 to .708 and .715 courtesy of Daryl Hallquist), some have a parallel bore and choke taper of 4 inches, and others a standard 2 – 2 1/2 inch taper.

Somewhere in the past issues of Gun Digest there is an article titled "Heat it and Beat It" about forming crude choke by simply swaging the lip of the barrel with a conical swage and a hammer. Understandably this was a single barrel with no rib. Despite the crudeness the results on the board were comparable to more sophisticated choke types.

Drew, magic occurs when a shooter stumbles across a gun with stock dimensions that fit him physically, handling that suits his physiology and psychology, aesthetics sufficient for pride of ownership ("---my gun is more beautis than youon" or my gun is uglyer than yourin"; whichever), fit for the shooter's main purpose, etc.

I'll opine that the Orre will deliver an improved mod pattern; not more or less. Until Dr. Jones published his book there simply was no way to really test patterns. We all did it on an experience judgement basis, but not hard, defensible, statistically valid numbers.

Drew and others, I have had two guns with the chokes tapered from the breech to the muzzle as Lefever described. Both were Lefever crossbolt [not sideplate] guns. One was a 5B the other an Optimus.

Daryl, do they pattern as the choke is marked/measure or do they pattern more open? In theory, the longer the taper the more choke effect is lost.

Yes, Daryl, how do the full taper guns pattern, especially with the best of modern wads and hard shot?

Sounds like a load of "hooey" BUT- My A.J. Aubrey 12 bore 30" Damascus barrels give amazing patterns with RST 2&1/2" No 8 paper loads, and not just on paper either- I love smacking incoming "Arch-angel" barn pigeons, and this Aubrey, grade unknown to me, has both barrels that pattern as tightly with my L.C. Smith Ideal "LONGRANGE" , shooting the same exact shells- One thing I can't figure out re: the A.J. Aubrey gun, there is no visible expansion joint on the top rib, near the receiver end- RWTF
