Colorado is a conical state: with the Dream Season if that is your choice is a fine rifle with Hornady FPB 300 or 350 grain and a load of 90 grains of Blackhorn powder will do the job on any of your game. I have had better results with the 350 grain for accuracy in my TC guns. I also prefer the Triumph as the best all round hunting gun as it is reasonably light and short and very dependable.
