How to open up a shotgun loading port - Franchi Affinity 3-Gun Mods

In this video I cover the method I use to open shotgun loading ports. This is not an end-all be-all One True Way, just how I do it. There are other great videos out there I would also recommend you watch, chiefly Jesse Tischauser's video series on the same subject:    • Video      • Video      • Video   The tools I used are: Brightly colored vinyl tape & 2" painters tape. Variable speed Dremel or equivalent die grinder 1/8" double cut carbide burr Dremel sanding drums, fine grit Dremel EZ Lock mandrel and finishing abrasive buffs in 180, 280 and 320 grit Dremel buffing wheel and white rouge, green stainless and blue all-purpose buffing compounds. Vise with padded jaws.
