I visited with the gunsmith that built the rifle and helped develop the load.Simply put,while the load is not too hot,it is hot enough to wear the brass out quicker,and 10 firings,might be pushing the end,if I continue to full length resize.Likely neck sizing would buy a couple more firings. He also said that the brass will show a ring above the web when it is getting weak, and that the brass in this area can get brittle over a lot of firings,because it is not annealed. Thanks again for the input.
