Congratulations!
That is a fine rifle!

First advice is to never hot rod it. It's not a Ruger #1 in strength.

Second, there's nothing on the face of the earth that cannot be killed, cleanly and quickly with a 500gr bullet traveling at 1250fps.

Third, get started on the Black Powder loads now. It's not the arcane, voodoo, super difficult method that some make it out to be, and it certainly will not rust your rifle immediately after firing. The Universal Solvent (water) is all you need to clean it if using properly lubed cast lead bullets.

Fourth, you can accurately hit stuff a long way off with those sights, you just have to figure out what the sight picture is for each range.

Buffalo Arms Co (BACO LINK) is the go-to source for a lot of what you will need.

Lastly, there are some really knowledgeable folks here, on the Shiloh Forums, and on Cast Boolits Forums who can give you general advice, or very specific advice on every aspect of he feeding, caring for, and shooting these great rifles.
