At the local range, you can only shoot from a bench. No prone or standing etc. I've used a lead sled before, but only for some of the harder-recoiling rifles. Since surgery is coming, those are gone and I haven't used one since.
I mainly use bean-bags (home made) and the caldwell sand bags front and a leather sand bag rear. To keep from crawling on the stock, I set it up a bit higher than normal.
At a friend's place, I can go out to 450 and do that prone and in other positions for practice and because not all the deer will walk up while sitting in a box blind!
