Fellow Armed Internauts:
Have been following the thread on .22 LR in a .22 Mag chamber, and have a
comment on how it can be done. I suspect the gun manufacturers wouldn't like
this trick, but it does work: I did it years ago with a Savage 24 in .22 Mag
and I suspect it will work in any other gun if you can get to the chamber the
Take a fired .22 Mag case, and with a fine file, remove the entire head until
what you have is an open-ended cylinder. This can be inserted into the
chamber to form a "sleeve" inside it. This case will accept a .22 LR case
just fine, and will provide enough shimming that the LR case won't split. The
length of the sleeve should be as long as possible, but not long enough to
interfere with extractor action, and of coure the entire .22 Mag rim has to be
removed to prevent the sleeve from being extracted with the fired round.
Shooting one or two .22 LRs will seat this sleeve tightly and it won't come
out until you deliberately remove it. This can be done by folding down one
edge with a fine flat tool and pulling it out with a pair of needle nose
forceps or a hemostat. It's possible a broken-case extractor might be needed,
but I didn't have to go this route.
This is of course a "jury rig" and not really a good way to do things, but it
works, and if you're in a position where you absolutely can't get .22 Mag, it
may be a viable alternative. Just be careful not to damage the chamber wall
One problem I did have was that increased clearance of the head of the .22LR
case from the extractor cause it to bulge a bit at that point--not enough to
rupture, but enough to cuase a noticeable dimpling of the head.
