I have been annealing for about five years now , as it was brought to my attention that it would make my cases last longer , and be more consistent , regarding interference fit , ( Neck Tension )....It also has made my "Bump" more consistent , to the point that I can control shoulder bump to within .001 on the majority of my brass
Not every piece , but the majority , by about 98% . I can live with that .
I now have over thirty reloads on my roughly 350 practice Brass , and the only issue has been gradually expanding primer pockets , where I then use the Ginex primers , till they go over-sized for them . The more consistent your cases , the more consistent the scores . Less than stellar S/D's run around 7-1/2 to 8 , and average is around 4 - 6 , so I know the problem is not the brass , or the load , but the loose nut behind the trigger .
