H3 - Welcome to the forum its good to have you here. That sounds like an excellent outfit you have there. Maybe Santa was good to you. The Omega will do it all. I would suggest you shoot 100-120 grains of loose powder such as Pyrodex RS or Triple Se7en 2f powder. Start with 80 grains and work up from there. Bullets I would suggest are the 200, 250, or 300 grain Shockwaves for starters. Some other ones to try are Speer Gold Dots, Nosler Partitionand Hornady XTP's but for sighting in I would START with the Shockwaves and branch out from there. If you want to shoot pellets, then start with 100 grains of pellets (2 of them) and later try three pellets if you want to try.

Put your scope on with Warne QD rings so it is easy to take on and off. Scopes with any magnification are illegal in Wisconsin for Muzzleloader season, sothis will be a great help.I shoot a Nikon 1X20mmm on my rifle during the muzzleloader season and a Nikon 2-7 during the modern rifle season when I use my White Ultra Mag.

Good luck with the rifle. Any questions you might have, just ask.
