It wasn't my rifle. It was made on a ZKK 602 action. I bought the original unfired .375 barrel for $100.00 - in 1975. The intire rifle weighed only 8.5lbs.with it's 4X Leupold scope. THAT'S why it belted me so hard. The owner fired 19 rounds of the bench. I shot it offhand - once.
: The load was 124gr. IMR 3031, 600gr. Barnes Solid - not 4831 as in the .460 WTB mag.
: I believe the .600 nitro, with good bullets is considerably more powerful than the .50. Those who've used them all, state there is a big jump from .5 to .577 and .600. FPE doesn't relate to killing power on animals that aren't suseptable to hydrostatic shock, ihmo. Yes, the .600 is over-kill.
