1) I have a custom 722 in 308 thats a 1/4" MOA rifle. It is a single shot that a silouette guy got tired of( why,,,,I don't know). What's a "real" long range limit for the 308 on whitetail? Not the "I chunked it out there 1500 yds. and I'll be dogone, it hit'em" answer. But real life dependable distance.
2) Should I ever decide to, what long range calibers can I rechamber this gun to and still use the bolt face and barrel. Even if I have to angle a long bullet into the action during feeding.
