Ultimate tactical hunting gun Part 2

In an earlier post, I discussed my plan to build what I consider the ultimate "tactical hunting" gun.  By that, I meant  a single firearm that could meet all my hunting needs.  The gun would have to be good for upland, small game, waterfowl and large game including feral hogs.  For more details on my criteria, see the past posting.

Here is what I have so far -

This started out as an older Mossberg 500 pump shotgun in 12 gauge.  The huge selection of shotshell ammunition made a shotgun the natural choice.  By simply changing shells, I can hunt anything from 4 ounce doves to 400 pound hogzillas. 

The barrel has Mossberg's choke tube system enabling me to use exactly the choke I need depending on what I am hunting and how I am hunting it.  Everything from cylinder bore (no choke) up to extra-full turkey and waterfowl chokes - even a rifled choke tube for sabot slugs! 

The gun was excellent working condition and had the tang-mounted safety that is standard in Mossberg shotguns.  This is a very practical place for a safety; I don't know why more manufacturers don't adopt it. 

I am not skilled at hitting airborne game using the traditional point-shooting techniques.  Besides, I wanted the gun to be as versatile as I could make it.  So the next upgrade was installing a removable scope mount with Picatinny rail.  On top of that I added a Tasco 30mm red dot sight.  The rail is removable in minutes, but low enough to remain if I take off the Tasco sight.  Should the scenario call for longer shots at predators or big game, a telescopic sight can be quickly installed.

More details will be in a later post.  Feel free to comment with your ideas - maybe I'll try it and we can all read about how it worked!
