Good thought Randy, after I had made my post that thought came to mind and then kind of wondered off. Your rifle should work just fine for deer and up close yots should be a one shot drop. Your lube mix sounds good. You don't need any of the super hard bullets, someplace between 30-1 to 16-1 will work just fine. Depending on your chamber, you might not even need to size the bullets, just shoot them as cast.

What diameter bullet would you recommend.
