Thanks guys,
Here's the deal..I hunt in a very tough WMA in FLorida..The hogs and deer are usually only seen about 20 minutes before good seeing light ..so I figured I'd sit in my stand with my 870 and 3 1/2 inch buck shot..After daylight i was going to quietly slide a slug in the chamber..When daylight comes ..my longest shot is 50 yds maybe..Ammo is getting hard to find so I only have 2 3/4 inch slugs..My Ithica puts them in groups of 3 inch..at 50 yds..but I haven't shot the 870 with slugs yet..

I did some homework on the slugs and yes 100% agree with Improved Cylinder being the best for slugs..

thanks guys,
