I have the older sled and put my snow chains (give or take 20 pounds) to better use.
I also added a $1.99 straps for extra security, not necessarily to clamp on stock and barrel but from falling off the rest. I accidentally knocked the rifle before and almost lost it.
As Jeff has noted, you cannot cradle the rifle accordingly. However, for my intended purpose, it works great.
I end up standing behind the set up to get a comfortable shooting position during load development. Once load development is accomplished, I use my bipod and shoot at prone then on a sitting position.
My set up also works great on barrel clean up as required between shot(s).
As far as stock damage, you are absolutely right something has to give and the weakest link is the stock. If you allow the system to recoil (reduce to a more manageable recoil and not eliminate), you should be OK.
In other words, do not use excessive counter weight. I have been using this set up since 2009 without any problem.
Hope this helps. Good luck!
