Crusader: I do not have any experience with the Windicator but I will not purchase and do not use Cor-Bon ammo.
I would pull the bullets from those 200 gn loads and either reload them with Winchester 296 and seat them deeply enough to get them to fit or toss the slugs and use the 200 gn cast swc slugs from either Colorado Custom Cast Bullets or Mt. Baldy Bullets over a Winchester factory charge of 12.4 of WW296 powder with a good crimp and a Winchester Standard or Magnum primer. Winchester chronographs these loads at 1335'/sec (barrel length unknow however).
I have used this load combination on hog, bear and whitetail, all from a 3.5" S&W, successfully. I would avoid cor-bon ammo like the plague. What you get ripped off for in purchasing one or two boxes of their stuff could get you started nicely in your own reloading and believe me, there is nothing that corbon sells or makes up that you cannot do better than by reloading your own.
Good luck andlet us know how it goes for you.
