I haven't found any additional info. on these cartridges. However I think the .35 WSSM would be a fine caliber for some company to bring out and chamber plus have factory loads available. Here in Ky we don't have caliber/cartridge size issues when it comes to Deer Hunting.Does any one know of any other sites that has info on any of these cartridges? I just looking to see what everyone is doing with them.
