After reading some posts of people having success with there plain barrel, bead sight smoothbores and slugs for deer I wanted to give it a test run.  I bought my Pardner 12ga for small game and upland bird hunting, I think I'll keep it just for that.  If I could find a smoothbore barrel with rifle sights then would reconsider.  I shot a variety of different slugs (chrony results posted below) and they all consistantly shot 7" low and 4" to the left at 25yds.  It grouped them consistantly but can't get a usable sight picture with this particular gun.  It was shooting 2" groups at 25yds with all but the Rottweil's which were about 1.5".  
Due to cost of ammo I gave up on rifled slug barrels and sabot slugs and replaced it with a muzzleloader.  That and the fact the sabot slugs don't live upto there advertised performance.  All the sabot slugs I tested last year were 200 to 300 fps slower than advertised with the exception of the Hornady H2K Heavy Magnum.
I was surprised with the smoothbore slugs. I sampled all I could find in my area.  The 3" Magnums with the exception of the Rottweil were BRUTAL in recoil! Wolf was the lightest recoiling.
