Just my opinion. I recently tried the Lead Sled DFT2 with a buckhorn sight Marlin 45-70, a scoped Remington .270 and Winchester .243 wssm, .223 wssm and 300 wsm rifles. I returned it to Cabelas the other day. For the price paid ($170), I wasn't impressed.
- heavy, big, awkward to carry out in the field. If you have a dedicated shooting range not an issue.
- Despite its weight, be prepared to carry even more weight to put on it or it will jump like a cat after each shot and you still spend time readjusting everything for the next shot.
- no eye relief adjustment. This was the biggest issue for me. I needed the rifle closer to me to fully see through my scope. I had to re-position my body off to the side and lean in towards the scope and it was uncomfortable. I removed the Shock Eliminator pad which positioned the rifle an inch back. Now I could see through the scope but then I lost a big part of the recoil dampening.
- the rubber barrel cradle strap was a beast to secure, like the shape of the hole opening wasn't cut right.
- after firing the 300 wsm, I didnt like how it recoiled. I had similar concerns as Wvmntnhick about it being too harsh on the scope.
As for pros, it does eliminate quite a bit of human factor, but not all. I did like the fine windage and elevation adjustments and it held the various gun makes securely. No marring. The skeletonized frame opening worked with the lever action and AR platforms would benefit from this too. All rifles sighted in, so it does work. There's just quirks I didnt like.
