[QUOTE="swampratt, post: 4227418, member: 15054"] So I (copper) pin cleaned a few batches of .223 brass and annealed about 400 rounds yesterday. Sorted my headstamp and by year for the LC cases. I brushed the necks with a spinning nylon bore brush after annealing and then lubed a bunch of LC 22 and sized them. Hornady Unique case lube. They full length sized like butter. Then I put a couple handfuls of Norma .223 cases on the bench and lubed them and sized the first one and then the second one and thought to myself man these are really sticking and realized I forgot to brush the necks after annealing. I did a test and removed the lube form 3 cases and brushed the necks and relubed them and they sized smoothly. I have known this for some time if a case that is resized is hard to extract from the die the shoulder will be pulled forward more than a case that slicks right out of the die. I measured those hard to size vs easy to size cases at the shoulder Ogive and the shoulders were pulled forward from .001-.003" more on the hard to extract cases. That is not all that bad but I have seen where longer shoulder ogive can cause a round to not go into full battery. You get that dreaded Click on an AR when you pull the trigger. I have to make darn sure the shoulders get pushed back all the way for ammo in my buddies AR. My bolt gun ammo will not run in his AR but will in all my AR rifles. [/QUOTE]
