I don't think it is the primer since at this point in the cycle the cases are fully in the dies. hence there is no rotation at this point.

- I only tighten finger tight on the shellplate no wrench. my press is a new Press SN 09743 When I say on the way up I mean that when the handle is down and I change direction to raise the handle is when it snaps. I am only using one hand, and not much force. This is the second in a row and it was broken on already sized and deprimed brass. (new starline) Here are some pictures: Hornady Split part 29 drive hub Split Hub 2

I have had my LnL AP for two weeks. I loaded less than 50 rounds and the drive hub split. I called Hornady and they shipped another drive hub. I asked them if they were aware of this happining because I was concerned since it seemed to be a weak link in the system I only load 45 and I use One Shot case lube so the press should not be under any stress. They told me that it must have been from a bad patch they had a while ago. I received the new hub and installed it. After loading less than 100 rounds the new one split. Now I will have to call again see what is up. The split happens when starting the up stroke I can not understand what the problem can be. Does anyone know what I could be doing wrong?
