Has anyone on here ever done much with cast bullets and the 7MM Mag and how did it work out for you. I bought a used Savage 110 in 7MM mag , I also have a Lyman 7MM 160 grain mold I use with a 7 X 57 Mauser. In my cast books I have found loads for both Red-Dot and unique powder for the Magnum. I am just looking for a mild plinking load but a little concerned about such a light load in a magnum case. I think Lyman NO# 2 alloy should be hard enough. I will most likely start out with a GC. I also believe with the large case volume and small amount of powder A Magnum LR primer would also be wise. Your thoughts on this.
Thanks
