For me personally, i dont view it as unresponsible of a hunter to use a match grade bullet for hunting, but its with a caveat that it has previous known 1st word experience to be effective.
The greatest example of this is the old Amax. Also, one benefit of shooting an a max or eldM is the cost factor. Sure i could shoot partitions or purely hunting based bullets, but they cost nearly 2-3x more and that means less time for me behinf the rifle, where the true factors matter (practice practice practice). The biggest disservice in hunting imo is a guy who shoots 20 rounds a year thru his hunting rig. Because even with the best hunting bullet or biggest cartridge, a misplaced shot is something you cannot fix.
A video of what practice can do is when i saw scott satterlee punch 2 rounds into an elk within seconds, straight into the boiler each time.
