I was thinking about porting my wife’s slug gun for her. It’s a Browning gold 20ga with a rifled slug barrel. Would this cause a feeding problem with it since it’s gas operated? And can it be done on a mill with an indexing head. Is there any kind of pattern to use or do the factories just try to make it look fancy? I’m a machinist and I’m taking the master course so I’m comfortable doing the work I just don’t want to ruin the barrel. Thanks for any help.
You can port with the indexing head. Most of the factories just make it look good. You will not want to angle the holes back as they will fill with lead and debris when fired. It should not cause any feeding problems as the gas system is well before the end of the barrel.
