A bit off topic, I did a lot with the .45 Colt. In any of the heavy frame guns, such as the big frame Blackhawk, Redhawk, Super Redhawk and some of the other .45 Colt guns that are now of print, you can easily surpass the performance of the .44 magnum and do it with less pressure. Here is a link to an article by John Linebaugh, probably the best authority on the topic.
