Hey guys,
Ive been having a problem with seating some 55 grain Hornady bullets (FMJ-BT with cannelure)
I'm using the Hornady seater die that also does a roll crimp.
I also size and trim my cases to 1.750 beforehand as well. ( I only size once before I trim, never after)
My problem is that when I am seating the bullet into the case, when the edge of the neck is within the cannelure region, it is ALWAYS loose.
When The bullet is seated above or below the cannelure though, it is rock solid. Now I WOULD just seat it above or below the cannelure, but the entire cannelure region is within the optimal C.O.L. region (the cannelure region fills between 2.200 and 2.260 of the COL)
I hope that made sense.
My Hornady die came as part of the 2-die 223 set with the Sizer/decapper die and the seating/roll crimp die.
Here is the link to it:

So anyways, i felt like the crimp wasnt going down far enough so i set the crimp part of the die farther down, but then the shoulder would start to compress and get fat while the bullet would still be loose with the neck around the cannelure part. (i can move the bullet up and down and spin it all around the cannelure region, but it stays in the cannelure region).
I have no idea what else to do to troubleshoot this. It just seems like the roll crimp isnt crimping hard enough.
I just bought 6000 of these bullets and dont want them to be useless.
Any help would be greatly appreciated. I shulda bought some bullets without cannelure *sigh*
