RE: Piked up the endeavor
Sounds like you are about all set. Please be sure to read the manual and know all the particulars about the rifle before setting off to the range. Be safe and shoot well.
I know nothing about that scope, although that is a high end scope I believe. It should work just fine.
Blackhorn is a great powder and those with that model rifle have been doing some outstanding shooting with that powder and the mentioned bullets.
