I started off using the 296 powder and switched to the 2400 powder because i use less powder in my magnum loads. One pound of powder goes farther. I use 2400 for my jacketed magnum loads and unique powder for my leadcast loads.

The winchester WLP primers can be used in the magnum and standard loads. I do believe there a tad hotter over standard primers. I don't use these primers when an empty case/light powder charge is used. I just use caution. Bill
