I can tell you without a doubt that if you handloaded that thing to it's potential with 200 gr bullets you'd have a vision quest after touching off the first round at the bench.
Been there, done that with a 700 .300 RUM in a McMillan edge. Oh, and it broke a VX III with that first shot too.
I also wear a scar on my head from shooting it prone from an awkward position. The elk fared much worse than me though.
