Average Choke Length for Lefevers
 

Just curious how long chokes are in the typical Lefever (side plate models). Anyone know? I have three 12 gauge models with varying choke lengths (and different choking) made in the years: 1896, 1901,1902 (if that makes a difference).

Any wisdom on this question?

Some Lefever information here

A 1898 Lefever G 12g was choked R .027" with a 3" length of constriction; L .036" with 4"

Daryl Hallquist has confirmed that an occasional Lefever 12 gauge has bores tapering from the breech to the muzzle (.756" to .708" left and to .715" right on one gun). Most have a standard U.S. .729" - .732" parallel bore.

Thanks! Mine have choke lengths of about 4.5 inches in the oldest, and in the neighborhood of 2.0-2.5 inches in the other two (from the first two years of the 20th century).

I suspect at least one of those has had its chokes opened. When chokes are opened, are they also (generally) shortened in the process? Intuitively (I know, not safe thinking), I would think not.

Garry: if the choke is opened (properly) from the breech with a piloted reamer, the length of the taper might be shortened depending on the profile of the reamer

If opened from the muzzle :( , not likely.

Garry- my experience has been that many original lefever guns pick up choke at or very close to 4” from the muzzle and taper significantly at 2”.
