She did try a Weatherby Vanguard youth but couldn't hold it up well in a standing position. I think the length of the barrel and weight distribution of the longer barrel had a lot to do with it.
I was going to suggest one of these as well. We have one in .223. It came with a spacer to lengthen the stock when needed. The barrel on ours is only 20 inches...I was a bit suprised when you mentioned a "longer barrel".
