.223 Issues

Any chance you bumped/deformed the brass with the seating die? You can eliminate this posibility by chambering a resized but not loaded brass. If an empty brass chambers easily, you may have to look at your seating die set-up.

A quick fix is to cut down the height of the shell holder, then make sure you use that shell holder specifically for the ammo you load only for that rifle. This can be accomplished fairly easily on a belt sander. Don't get too crazy though, just make small adjustments at a time until you hit the correct height. The shorter shell holder will allow the shoulder to be bumped back more and should solve the feeding issue you are experiencing.

Thanks for the info on this, the shell holder was an old RCBS one and it must of been a little higher than a Lee holder so the casing wasnt able to size all the way before it hit the bottom of the dies.

I have never had a problem using Lee dies on any of my semi autos. My AR just pounded out a 0.75" group at 100M in the wind at Connaught. Boomer is 100% right about sanding down the shell holder, Redding sells a set of custom shell holders for about $60.00 IIRC that accomplish the same thing. One piece of advice, get the Lee factory crimp die if you are using the ammo in an autoloader. Very bad things can happen if you manage to push the bullet in deeper before firing.
