i have a limited amount of reloading experience and have recently purchased a belted magnum chambered rifle and have zero experience with a belted case. i understand (i think) that not actually full length sizing with a full length sizing die is important for case life. I've done a fair amount of reading and I'm still unsure of the process of sizing off the shoulder. i was hoping it wouldn't be too time intensive of a task for someone to type/link a beginner's how to guide. thanks for the assistance.
