I remember my dad telling me that when he was younger, most everyone used the .410 for fox. he said that they called a sxs .410 a "fox .410". I asked if he was meaning that they were fox shotguns and he said no, just that everyone used a little sxs for fox hunting, didnt really say why they prefered them, just that they all did. So for chrismas one year I bought him a stoeger "fox .410". (even though he doesnt hunt fox). It may just be a local thing, alot of places use it for deer too, in this case they all used them for fox, a local preference? most likely /ubbthreads/images/graemlins/confused1.gif
I personally love .410's and think they are a very capable gun, as people have stated, when used within its limitations.
I generally dont shoot too many slugs out of mine, but if you are looking to shoot them a full choke is going to make accuracy a bit tougher than say a mod, or IC. It seems that a alot of them now are going to mod/IC lately instead of full/full.
My new gun, which if it ever makes it in county, is a o/u that im going to use for coons. ( at night only allows .22lr or .410). Once i get it set up the IC is gonna be a slug, the mod is gonna be Shot, and my partner will have the .22. (ill most likely carry one of my pistols too /ubbthreads/images/graemlins/grin.gif JIC )
I think that the range of a .410 slug may get you 50-60yds on a fox IF you practice alot, fox arent too big. /ubbthreads/images/graemlins/grinning-smiley-006.gif
If you dont shoot one alot I would suggest something else along the lines of the guns already listed.
Good luck and have fun.
