Daveo26 Posted August 26, 2017 Report Share Posted August 26, 2017 Does anyone know or could anyone measure the hole in the end as of a .410 shotgun mod for me please? The outlet of the mod diameter is what I need to know. Thanks Quote Link to comment Share on other sites More sharing options...
Dave66 Posted August 26, 2017 Report Share Posted August 26, 2017 Internal diameter of the muzzle end of the moderator is 13.95mm. Gun is a Mossberg. Hope this helps. Quote Link to comment Share on other sites More sharing options...

Old farrier Posted August 27, 2017 Report Share Posted August 27, 2017 Don't make the hole to big Try the same size as wad / bore Experimenting is good 👍👍👍👍🤗😊 Quote Link to comment Share on other sites More sharing options...
Daveo26 Posted August 27, 2017 Author Report Share Posted August 27, 2017 Well it works very well Stayed in one piece, no issues with the sizes. Job done Quote Link to comment Share on other sites More sharing options...
sitsinhedges Posted August 27, 2017 Report Share Posted August 27, 2017 I seem to recall that when I made my 20g moderator the hole was copied as 1mm larger than the one in the end of the barrel. Quote Link to comment Share on other sites More sharing options...
