I have been using my Mossberg 590 as my primary tactical shotgun for matches, it has tritium ghost ring night sights made by Sage International. For tactical uses I can hit center mass all day long with 00Buck out to 50 yards and using slugs hits milk jugs offhand at 100yards is quite simple, I'm pretty effective using slugs offhand on milk jugs to about 140-150yards. I use 2 3/4" shells for tactical use, Winchesters for heavy practice, Federals with Flight control wads for best accuracy at all ranges.
I have been hunting ducks and geese with this combo for the last eight years, only modification is plugging the magazine to accomidate two shells, my comments for hunting:
-ghost ring sites make finding targets incredibly quick, and is very instictive for me to line them up and make hits out to 50-60yards on ducks and geese.
-because I am limited to a 20" barrel, I need to use 3inch magnum shells for hunting and a heavier shot, I usually use #2 steel shot for ducks and geese, allows me to reach out to about the same effective range as my buddy who shoots a 26" barrel with lighter shot.
-reliability has been unbelievable, the gun has been through rain, snow, mud, sun, heat, cold, everything. Always works.
Took up shooting sporting clays a few years ago with the same gun and sight setup, after all the laughs subside on the range when I start knocking pigeons down from every angle, especially the bouncers that everyone avoids, I'll call out a bunch in a row just to hush all the ney-sayers with their $3000 custom shotguns and huge barrels.
D or just have him install choke on my 590 and plug the mag. LOL
