Having a lever and a pump in 45 Colt, I've been tossing around an idea of having a semi auto for the same cartridge. I thought for sure someone on the net would have already designed and built one, but I cant find anything. Contemplated a design based off the Ruger 44 Mag action, but a lot of metal work would have to be done, and I don't know if the bolt face can be opened that much more. The action would most definitely take the lower pressures. Just imagine lobbing 300grain bullets as fast as you can pull the trigger. Any ideas?
