I have had two Ackley's and one Wby. There is one significant difference. The Wby chamber is cut about .02" shorter than the H&H and the Ackley, which are both the same. Occasionally you cannot chamber uncrimped 375 H&H in the Wby chamber whereas you can in the Ackley. This is only an issue if you are in some remote location and are stuck with the H&H handloads (most factory H&H ammo has enough crimp to enter the Wby chamber). If an H&H is rechambered then there is no issue either. The throating of the Wby is a little longer too. Both are pretty much wildcats so I would get the Ackley cause it looks wilder.
