I have not resized them before this last loading and have never annealed them. Possible that they work hardened by many loadings? From this batch of 20 I had 1 hull split on the last firing. All of the others look to be just fine. I buy cards and wads and use 11 ga. for the 12 ga. brass hulls. Prior loadings they seated with resistance and gave good compression and seal. Last loading they seemed to be a bit loose. That is why I am thinking about a resize and partial anneal. (It maybe possible that these hulls are finally just used up?) They have certainly paid for themselves with many loadings and lot's of enjoyment on the course and in the field. I may just break out a new batch of hulls. I've had the new Remington's for 30+ years and it may be time to dip into them. I've loaded several old Alcan brass hulls and they are really nice. Have two boxes of them unfired in my collection and I think I'll get them out also. Paper hulls are the best for black powder but there is just something about all brass hulls and old hammer guns.
