Hi there. I’m not new to reloading but I’m new to to this site and case forming. I’m in the process of forming 308 to 6.5 creedmore. I’m using 7mm 08 as step between the two. I am happy with the results but I need to understand two things. Do I need to anneal? And what is neck thickening? And how to fix it. If I have a 308 case with no blemishes, it produces a nice product that only need to be trimmed
Thanks
