Thread: Loading .577 snider?

Hey guys, im sure some of you have experience with this.

Im wanting to make up some .577 snider ammo.

My plan is to load a 525gr .58cal projectile behind perhaps 65gr of "holy smoke" FFg black powder. (the hornady great plains .58cal projectile) Iv never done anything with black powder before, but I understand I might need to use some kind of "wad", and/or some kind of case filler?

I guess im seeking info on wads or "fillers" in black powder (rifle) cartridges in general...

Is some form of wad, and/or some kind of filler absolutely necessary? What is its purpose? What are the pros and cons if its optional?

If some form of wadding or case filler is the way to go - what might be a good choice to use? Is there anything I might already have around the home, or something readily available that could be used
Im obviously a complete amateur when it comes to this stuff, and know a bunch of you will no doubt be pros
Cheers..appreciate the advise.
