I use a lead sled. It's the Caldwell Lead Sled DFT. For me it serves two purposes. Figuring out heavy loads can be hard for the old shoulder to handle. But to me the most important purpose for the lead sled is to take out the human error aspect. Heck, I'd be willing to lock the rifle in a vise if I could! I can't hold a rifle still enough to decide which is the most accurate load.................so the lead sled lets me "park" the rifle on the bulls-eye and only be responsible for lightly pulling the trigger. I'd use a trigger release if I could figure out how to make one work for all my different rifles. If I get a round punching multiple shots in one jagged hole, then I'll know it's up to me to do that in the field. At least I don't have to wonder if the missed shot is the fault of the round or the rifle.Anyone use something like the lead sled when working up a load. Seems like they would work good even on lite recoil, but would be great on the heavy stuff. I like my guns to shoot better than me and this would take some of the human error out of it.
Which is why I slide the forward support structure of the sled back to a point I can rest the rifle just forward of the lever.I need something better than I use for load development. For that reason I think this is a good thread to read as I consider what I will finally get.
I'm thinking a single support might do me better since I find that support directly under the joint between forearm and receiver gives me best accuracy and a full sled puts support forward of that juncture. YMMV here more than it does anywhere else. Heck, it's likely to vary from gun to gun, let alone shooter to shooter.
