Caldwell "The Rock" plus rear bag. Simple and heavy.

I made my own one piece rest, weighted. I wouldn't go back to bags for dialing a gun in again.

you can make lighter yet still decent bags with dry seed corn or pop corn as the filler they are much lighter how ever the mice may get at them if you store them in a garage another good but not too heavy bag is a kneeling roll

one of the bags I have heard about being a big deal in the PRC is the Game changer https://www.armageddongear.com/Support-Bags_c_53.html

not cheap but a fairly light turns so many objects into a steady rest more than you need for god bench shooting but when you see what the competitors are finding works it is interesting

remember they have to carry everything through the course on them no cart

Get GOOD HEAVY FRONT BAG AND REAR SAND BAG YOU CAN PINCH-IF YOU ARE WORRIED ABOUT RECOIL PUT A 25lb of lead shot behind the gun-it works awesome!

I agree that a lead sled is not the answer to tolerating recoil. Go to a lighter cartridge, or practice shooting standing up, off-hand or with shooting sticks. Recoil is less noticeable when you're standing than when sitting at a bench.

When I was planning my trip to Africa, I worked up a load for a .416 Remington Magnum. I was only able to do this in such a short time because I shot mostly from sticks. In Africa, you shoot from sticks anyway, so I was able to practice that while also working up the load. Two birds, one stone.
