I understand there comes a point of diminishing results. Granted.

But....If I set a deer up at 50 yds and you had to iron-sight him with a 4" pistol barrell.....a 12" pistol barrell.....or a long rifle......which would you choose...and why?

Also....to take it to the extreme.......imagine you cou;d actually place the ssight pin ON the target. Actually ON the target. Wouldn't that be as accurate as you could be????
