A bushing die would be great.
I personally prefer not to buy Whidden if I have a choice, not happy with their products vs. their price. This, from using their 260 and 308 die sets, not the Sherman. Been very happy with my Forster sets.
But what is that actual cost savings with Hornady? There would have to be a substantial cost savings there for it to make sense in my opinion, and if the volume of sales of the Hornady, that were pulled away from the Forster dies,ended up hurting the price or availability of the Forster dies. Then in my opinion, that would hurt the Sherman cartridge.
