[QUOTE="Unionsparky46, post: 2743929, member: 125736"] Pancaked primer = overpressure. Hot meaning over pressured round. A lot of carbon around the neck can show this as well. Been loading the 300 win for several different rifles over 20 years. Sticky bolt usually meant over pressure. Won’t chamber round even after a FL die was used on brass meant bump shoulder back .002 with a FL bushing die. Most of my brass for one of my hunting rifles is on its 6th firing and twice annealed. I’ve had shoulder and neck failures due to pressure as well. Still have the brass as a reminder. Even when the manufacturer says it’s cool to cram it to the lands, your rifle might not think so. I definitely don’t think it’s a chamber issue. Back the bullet off the lands and start over. Good luck and be safe! [/QUOTE]
