[QUOTE="longbowelk, post: 1209413, member: 41272"] Update: I loaded up a 162 gr Hornady with 45 gr IMR4350. The bullet was to the lands. I took a measurement and it was 2.889 to the ogive. COAL was 3.4593 After firing, The case showed a slight ring at bottom. I need to back off the powder. However, I took some headspace measurements of the brass with my Hornady Headspace gauge. I got 2.136 Some of my previous bullet fired cases that weren't cracked using the same 162 but not to the lands got the same 2.136 I read on another thread the Original Ackley was 2.144 & new Nosler is 2.13 Comparing mine to the original(what I am suppose to have) looks like I have .008 headspace which is where the problem is of why I can't fire factory ammo. Any thoughts? [/QUOTE]
