Hey, I am getting ready to purchase a shooting rest. I plan on mainly using it for checking zero on my rifles, and when working up loads while reloading, which can involve the need to shoot 50 - 100 times through the course of an extended session, to narrow down a reloading recipe that works best for a particular rifle. I am considering the Lead Sled DFT and the Hyscore DLX Precision shooting rest. The Lead Sled DFT seems to be well regarded. Anyone have any experience with the Hyscore? Any opinions or experiences with either device?
