Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_203_112 ( id number, "choke" text, "constriction (inch)" number, "percentage of lead shot in 30-inch circle at 40 yards" text, "identification (notches)" number, "identification (stars)\n(spanish shotguns)" number )

### Question ###
what is the difference in percentage of lead shot at 25 yards between cylinder and skeet 1 barrels ?

### Accurate SQL ###

SELECT ABS((SELECT "percentage of lead shot in 30-inch circle at 40 yards" FROM table_203_112 WHERE "choke" = 'cylinder') - (SELECT "percentage of lead shot in 30-inch circle at 40 yards" FROM table_203_112 WHERE "choke" = 'skeet 1'))
