"choke bored" rifle barrel

[sammy]

Is there such a thing? I refer to the seeming constriction in the barrels' last few inches when the cleaning rod needs a harder push to get through.

There was a German anti-tank gun of late WWII that had a tapered bore from 28mm down to 20 mm or something like that.

Anschutz barrels are choke bored.

For cast bullet and/or black powder shooting, i prefer a barrel that gets a little tighter towards the muzzle.

It is not unusual for a precision rifle barrel to be cut and crowned at a point where the bore is a bit tighter. If the muzzle is created at a looser spot, accuracy is likely going to be reduced. About the only way to generate a choked rifled bore is by extremely skilled lapping, by using Anschutz' techinque, with the enlarged exterior muzzle diameter.

Most precision, as well as high velocity air rifles have their barrels swaged tighter at the muzzle. bearhunter
