Two pages of comments and not a bit of useful information given by you to help you diagnose the problem. Just that you get mis-fires.
What do the firing print strikes look like on the cartridges that failed to fire? Light, normal, non-existent, does the rim appear bent on both sides?
Have you been dry firing the gun and caused an indent in the chamber face that has removed the anvil effect? It can be repaired if you've done this.
Perhaps you do just have a bad lot of ammo but we will never have a clue unless you provide more info.
