I don't think it's a bad design. It's certainly a jack of all trades and master of none, but taken as a whole it's an admirable round. Not very many critters will take a 180gr .30 Cal bullet launched at 27-2800fps, at any reasonable range, and walk away from it. Not many things were likely to hunt NEED it either. BUT should you need more and you've still got 200-220grn options. If you want to be able to shoot rabbits to grizzly with a single gun (also not common anymore, but much more prevalent in the past) you'd be hard pressed to find another cartridge that can do those things as well. Especially considering the construction of your average small bore bullet from the time of inception till perhaps the partion hit the market. This is of course my opinion.
