There are some practical problems with this.  LOX is easy to get, but
LNG is not so simple.  Oxygen boiling out of a storage dewar is a lot
less of a problem than natural gas.

There are people, not sure if you know them, who have mixed propane
and LOX in two-liter bottles. The two are not miscible the way LNG and
LOX are, but my understanding is that they mix better if you screw on
the cap and let the bottle warm up some.

with a 30-06 round and every time with a tracer round.  The bang is
about equal to a 50-pound box of dynamite.
