Which air rifles have choke - and why?

[Antoni]

Shotgun + Choke, yes. Understood.

Why would an air rifle need a slight narrowing of the bore at the end of the barrel?

Of self respecting air rifle models, do some or most or all have choke?

As to who make them, HW and Walther Lothar both sell choked barrel blanks.

As to why, erm let us know , I believe the notion is it reforms the pellet on exit reducing pellet fussiness, I may be wrong on that as I have never heard a definite statement as to the reason.

All I know is after testing a choked barrel for grouping then cutting the choke off and re crowning, the groups did not change one bit, so now I only buy unchoked barrels from Silco as they are cheaper.

I've always assumed that it was to lesson friction on the pellet as it accelerates up the barrel but then ensure the pellet contacts the groves enough to impart spin.

some HW ones get choked when the front sight mount grooves are formed so I have read before.

That's an internet myth mate,
I buy barrels from silco you buy them choked or un choked http://silco.co.uk/products/-BARREL-...WEIHRAUCH.html

I have a hw100 with no grooves, that's choked, I also have a HW98 with no grooves that's also choked so pay no attention to that old chestnut.

I meant the front sight mounts on the hw99s and other break barrel rifles . like this http://img.photobucket.com/albums/v7...psbe6b99af.jpg


Unintentional chokes
So far, I’ve been talking about chokes that are intentionally put into the barrels, but there are the unintentional kind, as well. Certain spring rifles such as the HW 80 and older versions of the Beeman R1 used to come with sights. The barrels of those rifles had dovetail grooves for the front sight swaged into the front of the barrel. When the swage upset the outside of the barrel to make these grooves, the metal inside the bore was distorted just a little at the same time. If you push a pellet through these barrels, you’ll feel it pause when it gets to where the dovetails begin. This isn’t a real choke, but it does feel like one when you test for it this way. Shooters have referred to these as choked barrels for decades.

this was not where I originally read it though.

Yes this is exactly right as the groves are not machine cut but pressed into the barrel. I have an HW80 that had a very tight choke and the result was that after about 50 shots accuracy would start going off dramatically, a good clean and it was back on song. I had the choke removed and the barrel re crowned and now the gun shoots perfectly with a wide range of pellets and has never had its barrel cleaned since.

I dare say some shooters would have similar accuracy issues and not make this connection.
