I have one of those Edger. Also have a .416 Rigby and a 577x3". You get use to the recoil. Just don"t try to shoot a box of shells through it every time you shoot it. I have fired all of mine from a bench. No lead sled. None were much fun.

One of my shooting buddies, 83 years old, swears by the lead sled. However, he recently purchased a SAKO .375 and broke the stock at the wrist on his first shot on the lead sled. I have two .375s, a London Rigby and a first year Super Grade Model 70. If I use the lead sled, I will make sure there is some cushioning before I risk a $2000 stick of wood.

The very reason I don't own or use a lead sled. If I were to break the stock on one of my big bore doubles I'd likely turn the rest on myself.
