Having shot various 45 Colts over the past 50 years I learned a couple really important things don't use soft swaged bullets and size all home made bullets .454 / and if you can find them buy factory made bullets sized .453. I've not fired any of the powder coated bullets through my 45 Colts , have no idea how they function.
