I have 8-9 458 moulds from 141 gr RB to the 535 gr 457132 NOE version .
Any 500 gr version at 1100 fps MV carries 1000 ftlb past 250 yd .
The Lyman 458193 405 gr , mine drops 412 a/WW and 415 with a softened alloy , is the most alloy , powder , and power level flexible bullet so far .
I expect the 45-500 FP to edge the 458193 out with its gas check .
As others have mentioned dead soft or close to it at Trapdoor levels should be enough for anything in north America short of a zoo break .......there was this ranch in Texas with a water buffalo on hand where an antitank rifle would feel a little insufficient after youve been close to one .
