otdrzmn04 Posted July 23, 2009 Report Share Posted July 23, 2009 what should the I.D. of the barrel be at the end of a smoothbore .410 for rifled slugs? this is just a rossi single shot but groups are no better than 8" at 20yds. i have been told to cut a few inches off the barrel and it would help but im uncertain how reliable this info is. thanks Quote Link to comment Share on other sites More sharing options...
