WellI got to use the new rest today, and it might be my shooting style or the way I use a rest, but I was not totally satisfied with the rest. I finally put a large rest bag in front of the back rest and that made it much better. I was shooting my Knight Disc, which while a shorter stocked rifle, should not have been a problem. The funny thing is, on the back of the rest is a carry handle. That is the part that gets in the way for me. Other then that the rest seems good and sturdy.

As for my shelf, yes, when a lot of the powder cans are full, the shelf can bend a little, but it holds. The rest of the powder stash is kept else where in an single container.
