I normally trimm the cases after the sizing step.
But today i have had problems with 264 WM cases.
When i size it (hornady new dimension full size die) the shoulfer collapses (seems to get "star" shape)
I unscrew a few turns the die, and sized a few cases. But when i tried to trimm this cases (to 2,490"), the neck becomes too short. I have other 2,490 long cases with longer necks.
Thanks in advance... Hope you understand the post, my english isnīt as good as i want...
