Solution:
The Hornady Die set 546349:
I emailed Hornady, their solution was to give them a call.
So this morning I called their technical line and this is what the conversation went like:
Dyjital: Having an issue with die set 546349 and crimp.
Hornady Rep: .300 Blackout, this die set has a 90" roll crimp ring, so unless you are using a cannelure bullet you will start to damage the shoulder.
Dyjital: That explains it, I was making sure I wasn't crazy, thanks for your time.
Hornady Rep: Even in these dies there will be more than enough neck tension to hold without a crimp in an AR.
Dyjital: Thank you sir and that answers that question. Problem solved.
So that's the solution to these die sets. No cannelure = no crimp. Even then with cannelure you can only add a little because of the 90* crimp ring. If more crimp is needed one must use a taper or a Lee FCD/Lyman etc made for this in that capacity.
Total call time (including prompts and the 15 seconds I waited for somebody to answer - I was 1 in the queue) was 3 minutes.

Original Post/Problem said:So my .300BLK dies I've got dialed in EXCEPT for crimp.
I've read the manual and the only thing I'm doing is crushing the case. I have one case that's been abused. I'll seat a bullet, attempt again to setup crimp. Crush the case, pull bullet, run it through the die to resize and straighten it out a little. Seat bullet, try again to crimp.
Apparently it's supposed to have the crimp built into it. All I see is a flat rim.
No taper like any of my other dies.
So does it look like this die set has no taper to anyone else?
Inside diameter is .321", larger diameter is .340" (approximates with calipers)
