The short answer is there is no proven replacement primer.... Each rifle is unique esp factory ones and will respond differently. If you are going to start over at least when you find one that works well buy a supply of the same lot and you will not find yourself in this situation again.. I have a good supply of powders, primers, bullets and brass for all of my competition rifles and the majority of my sporters----nothing is worse than having to worry about finding components when none are to be had..
