[QUOTE="longbowelk, post: 1208658, member: 41272"] I understand the process you describe. I can do that. However, this rifle was built with an extended throat. A 162 gr Hornady bullet will barely be in the neck. I do have some 175 Sierra's that I may see if they will do better. This was suppose to be the original P O Ackley but is now in actuality a P O Ackley wanna be that is sort of close but not exact. Therefore, I am encountering these problems. If I load 75%, seat bullet into the lands I should get a case that is fully ready to take on acceptable AI loads and should not see any case damages. Keep in mind that due to the short mag and extended throat the bullet will be seated .2 off the lands and not .002. A 162 gr Hornady loaded to the lands shows COAL at 3.4585. Maximum COAL in the mag is 3.258. That defys reloading logic. I am no expert but the guy that built this rifle 1st should not use this action for a .280. But since he did he should have took into consideration the short mag and not put a deep throat on it. My gunsmith says he can take a thread out which should help but not completely. [/QUOTE]
