A dot also allows you to shoot with both eyes open which is a plus on running game...
This is something I've never understood - shooting a scope with only one eye open. I've always shot everything with both eyes open and with a scope you throw it up - your scope eye sees the X-hair while your "off-eye" sees the game and you swing the X-hairs toward the target - bingo.
I've try teaching that to several shooters and for reasons I'll never understand, they just can't get it to come all together.
In benchrest I'd watch my flags and at 200/300 yards I could also see the flags from the guys next to me in my scope - I could also watch most of the field with my "off-eye" and could see a wind change coming sometimes - sometimes that wind was mighty stealthy.
Do most here shoot both eyes open with irons, dots, peeps, scope or whatever else is on top of that barrel?
