I want to make up some .38 Special, snake shot loads using Speer shot capsules. I have an abundance of Magnum small pistol primers that I would like to use up, to conserve my supply of standard small pistol primers. I will be using Titegroup powder. I know I don't need magnum primers, but would any harm be done by using them. Essentially I just need the load to go bang, as long as the mag primers don't blow holes in the pattern.
