I used a Wolverine for a few years.Great starter muzzleloader.I did exactly as you are considering and went with 1 load for deer and elk.Made sense to me because around here the deer and elk seasons usually run together.

I used 100 grains of pyrodex,with 315 grain sabots.They shot very well for me in that gun.

You have a lot of options though.777 Powder is 1(cleaner&hotter) and the powerbelt bullets are another. I bought a Knight Bighorn Saturday at Bobs.I took the advice from a fellow ml hunter with 1 and started out with 120 grains of pyrodex and 295 grain powerbelts.These are rated to use up to 150 grains of powder.Amazing acurracy with that combo.I then substituted 100 grains of triple 7 for the pyrodex and was still very satisfied with the results.

So as you can see different powders and bullets work different in differnt weapons.
If I were you I would start out with a bullet to your liking then 90-100 grains of pyrodex.Or 80-90 grains of Triple seven.Adjust your powder charge up or down 10 grains at a time till you get your rifle to shoot best.

Most of the sighting in stuff should be on a vidio you got with your gun.along with the recomended loads.Just remember to run a spit patch between rounds.

I'm sold on the powerbelts.And the triple seven powder.The powder is way cleaner than pyrodex and very little smoke.A knight rep told me to use 10-20% less than I would of Pyrodex.Whatever you do dont exceed your rifles rated powder charge.

When you find a load you like,that shoots well,its a good idea to mark your ramrod after you put a load in.That way you can always tell if you put in a charge or bullet .Plus keep from putting in a double charge.

The other thing is the caps.I have been using the waterproof German caps and have only had 1 ever fail In my opinion they are the best.The name on them is Vorderlader-Zundhutchen, Dynamit Nobel is also on the label.They come in a red plastic pack with a green label.

I remember the 1st time I loaded my muzzleloader.I poured 100 grains of pyrodex in my hand.After looking at that much powder I was a little iffy about pulling the trigger.It went great thogh,and I've been hooked ever since.I could go on a lot longer.But still consider myself a novice in muzzleloading.I'm sure you can and will get more great advice from this board.

If you have anymore questions just ask,and I'll do the best I can to help out.
Good luck with your muzzleloader,I hope you enjoy it as much as I have mine.
