You want something that points quickly, sights lined up for you.
But you want something which has enough muzzle weight for a smooth swing, and to help stay on target to see the impact, and for another shot.
I use iron sights on my .30-30, .444 Marlin, 8x57, 8x60S, .30-06 and other rifles, but do have some 1.25-4x and 1.5-6x scopes for use, too. An 8mm firing a 200-gr bullet at 2,500 fps, or a 265 gr bullet at 2,200 to 2400 from a .444 will flatten the biggest boar, and a much larger bear. Likewise for a 9.3mm
