Yes it is possible to get your old cowboy rifle or .22 shooting straight again, without replacing the original barrel. Lower pressure rounds can successfully be relined.
This particular one is a Stoegar Luger .22. It has a horrible chamber, probably a Friday gun or chambered with a worn out reamer. It did not want to feed or Extract!!! The conclusion was simple, it needs to be re-chambered. The barrels on these are press fit into an aluminum frame, so after trying a couple of standard methods to remove the barrel I decided it was to risky to try anything “unconventional” as the aluminum frame could be split accidentally and well that’s it for the ole Stoegar.
The solution turned out to be rather than set the barrel back and rechamber on the lathe, why not just reline the whole barrel, set the chamber right in the barrel liner and slip it in!!!.
The picture above shows the Stoegar Lugar with the barrel liner in place. A special drill bit is used to cut the old barrel & chamber out. then a new manufactured barrel liner is slipped in place and secured with slow hardening epoxy. You have to use slow epoxy for a couple of reasons.
It allows you time to line everything up
It dries stronger
This picture shows the chamber, I packed clay into it to prevent the epoxy from filling up and ruing the barrel.
after the work was done the Stoegar Lugar extracted perfectly, but still had some jamming problems. To make it more reliable in addition to the relining the barrel it was ramped, recoil spring replaced as well as the magazine springs. It is now a pleasure to shoot.
A small pistol like this can be done for around $200 bucks, rifles around 100 more.
