Curious if any one has used either of these rests for sighting in or working up loads. I already know the main differences between the two. I'm just curious if any of you have had any experience with either of these rests. The 360 degree arm is a neat feature on the Fire Control, but I'm not sure if it's with the extra cash. I'm not worried about recoil. I'm mainly getting this for a solid rifle rest. The Lead Sled has nothing but great reviews it seems, and the Fire Control seems to have some bad reviews. Thanks in advance for any help you can provide! Also any other suggestions are welcome. I'd like to spend $500 or less on the rest. THANKS!
