I am going to switch from my red dot scope to a leupold 2-7 x33 scope on my 12 gauge winchester 1300 pump shotgun after a battery failure and eyesight getting worse... I would like to hear some reviews on bench rests and bore sighters.... With the cost of slugs it will pay for itself... I dont want to go thru the sore shoulder and flinching trying to get it sighted in shooting slugs.. I dont mind it at first but after several shots your shoulder takes over your trigger finger and you start jerking the trigger instead of squeezing and start getting fliers and second guessing your shot placement.. any help would be appreciated!@
