My son wants to hunt deer this winter and I remembered I had an old CVA Staghorn 1:32 twist .50 cal in the gun cabinet.
I got it in a trade (here I think) years ago and never fired it.
It uses a percussion cap for ignition, and has a removable breech plug.

A few questions:
I couldn't find a breech plug/nipple wrench that fits it well in my cleaning box. I found one that I got it apart with, but the wrench is a bit too short to be efficient.
Would this wrench fit it?

I hope to find a fairly youth-friendly load for it (he's only 12), probably something in the 70-90 gr range using Goex ffg.
What bullets might be good for accuracy with the 1:32 twist.
I have a variety of sabot/bullet combos and Lee R.E.A.L. 250 & 300 gr molds.

Thanks for any help & suggestions!
