Correct.
This is why I was advising in my previous post warning you of the scope hit in prone, to
sit low at the bench (12" to 18" off the ground). It forces you to keep your back upright, hence able to roll back under recoil; it puts meat between the recoil pad and your collar bone; and it prevents you from crawling forward on the stock toward the scope.
Actually, in the old days, the British gun makers had
standing benches that they used to regulate the double rifles. That worked pretty well.
As to portable shooting bench, I am personally really happy with the MTM "Predator Shooting Table." It is cetainly not as solid or steady as 's bench, but a heck of a lot more portable if you do not own the place where you shoot. Simple, inexpensive ($65) and about the right height when sitting on an ammo can. Just put a simple MTM or Caldwell front rest ($25) on top of it and Bob's your uncle
I personally do nit use lead sled. I am concerned that they stress wood stocks too much, and - more importantly - they change the dynamics of the recoil so much on high recoil rifles that the zero your get on lead sled does not always reflect the zero you will get shooting from field positions when the rifle is already in rearward / upward motion
before the bullet actually leaves the barrel...
Just my $0.02...
