I am having a problem reloading .223. My reloads will not fully seat in the barrel. If I try to seat them they become so jammed that I need to run a rod through the barrel to remove them. Here are the specs:
Not chambering would suggest that you are not full length sizing the cases, or possibly do not have the seating die properly adjusted, causing a case bulge. The 223 is an easy round to reload. I have cranked thousands through my Dillon 550.
Get the Wilson case gauge to set your sizing die and to check for the need to trim. I'm a rifle newbie and just reading the instructions from Wilson taught me a lot.
Case length is a little long, trim to 1.750. It looks like you crimped it. That could make the shoulder "mushroom" out a bit, also a symptom of too long a case. There is no need to crimp a .223. Proper tension is all that's needed.

While I agree that a crimp is not needed, if the ammo is going to be used in a mag fed semi, it is good insurance against higher pressures due to possible bullet setback to have a slight crimp at the canelure in the off chance that a worn case with improper neck tension slips by in the loading process. Every military round of ammo I've ever seen is crimped both at the bullet and the primer.....there must be some known value to it.
The round pictured does appear to be excessively crimped and that coupled with the lack of trimming, has made the neck dimensions too large.
Trim brass to proper length and crimp into bullet cannelure only. If the bullet has no cannelure, apply very light crimp; do not deform brass or bullet.
