The ** is improved modified; the *** is modified. Sounds like someone did open them.

Only way to know is to have the bores and muzzles measured and to subtract the diff. and pattern the gun. Skeet 1 on a 20 should be a .004 between the bore and muzzle; IC should be .006. At 20 yds., a 28" killing pattern, not counting flyers would be about skeet 1.
A 25" killing pattern would be IC
