Agree whole heartedly,
Moon. Off hand I can't think of one of my iron or peep sighted rifles that does not have a white dot front. Though, I will admit to using typewriter "white out" fluid to do the same thing with the oft encountered gold bead. The Winchester Model 62 below has a Marbles (I think) white bead front...could be one of Lyman's though. It's the lower one in the attached pic. The upper pump is their Model 61 sporting a Redfield 3/4" .22 4x scope.. The lower Pic is of my Winchester M-65 in .25-20. With the peep and the hood off the front ramp, it's sure-fire woodchuck medicine if I've got my sneaky moccasins on.
