am i reading it correctly? that the bore is 20 gauge if so the you got a 20 gauge rifle

the other case the others are talking abouth is an alex henry special 20 gauge x 577
the case is 2 3/4" long and is basicly a 20 gauge neckede down to 577.
marrakai has a good story abouth his on his web site with some good tips to get it shooting again.
i got one as well you can find it @ alex henry return to life. on this site

if you got a 20 gauge dbl rifle look at the gauge rifle section.

what ever you got it will be a gem.
