My answer was on the rifle iron sight pictures I use in hunting game.
I'd like to see you, or anyone else, accomplish your accuracy benchmark using that type of rifle.
It's not the iron sights, but to hit a 6" bull 100% of the time from 150 yds, is no small feat. Very few shooters using a bona fide big game hunting rifle can do that, regardless of sights.
I'd be willing to challenge anyone who thinks he can to a 100-shot match here. I can only name a dozen or so folks that can do that, and maybe none with a DGR, I don't care what sort of sights you have.
