Wow! I can't believe everybody hates the new dimension dies. I have 2 sets and have never had a problem. A little reflection on it has made me pause. My dies are in 7-08 and .284 Win. Both have short necks, I tumble my cases and lube the neck with mica before sizing. I also load cast bullets so I expand the case necks with M-dies more often than not.<BR>I'm glad you guys brought this up. I might consider sticking with RCBS dies in calibers with longer necks.<P>Dean
