I will be ordering a new Ruger Black hawk in 45 colt this week, still up in the air on barrel length, but it will be 4.5 or 5.5 inch, and was thinking of getting a 250 grain mold for it, something like the Lyman #454190, would this be a good choice, or should I go up or down on the bullet weight, this gun will mainly be for punching paper , or a close range White tail deer gun. I cast other bullets 9MM, 38/357. 45ACP, and .308, but this would be my first 45 colt. Thanks in advance.
