Frankly I don't believe anyone that says "X tastes nasty" anymore they're so often full of it. How many folks have you heard talk down pronghorn? Maybe they just toss theirs in the back of a truck in 90F heat or something and its partly rotten, dunno, but what I do know is we eat multiple pronghorns a year and they taste just fine. No game meat is gonna be the same as their dry aged beef or such but doesn't make it dog food or something to let rot IMHO.
The one ram I've gotten so far (~19" so nothing that old), I've used the rounds in the rear to make up a curry that after 10hrs in the slow cooker was tender as anything I've ever eaten and of the 6 adults that ate it (happily) no one noticed any disagreeable flavor but we all joked with all the curry it'd be hard to. So on that side of spicing/softening cooking I know it can be easily enjoyed. When butchering up the backstraps they seemed soft as any other critter so I'll try actually grilling a piece out of curiosity here shortly (been hectic). I bulk froze most of the trim for now, but I'll thaw and grind some sooner or later and try out tacos, etc. and I anticipate it being just fine. I know I have a fallback (heavy spices and slow cooker) if needed. I took all the meat (rib meat and neck meat) and heart out, saw no reason to let anything lay in the field I'd eat of another critter.
