One other thing I found when forming cases from 30/06; if I did it fast, I got fewer dents. Slam it into the die than yank it out right away. This in the C-H die. Except for the lack of a vent, I really like the C-H dies. I have them in 30 Newton as well and they are just fine.
My rifle is based on a slightly modified Winchester 54 (Mauser bolt stop, M70 bottom metal, new bolt handle) with a Benchmark barrel. I put it into an Echols Legend McMillan stock which is a nice enough stock but difficult for me to warm up to. I'll probably make a walnut stock later. I am quite a fan of Newton's cartridges; especially the 256 and the 30. GD
