Reports have come back that some barrels seem to prefer the flat base and some the dish base. So the 29.0 are dish base and the 29.5 are flat base. You may find a barrel likes one over the other. One report is that the RAW liked the dish and the same shooter's FX seemed to prefer the flat. Other FX reports have been dish shot well.
We decided to offer both.
