Re: Need some help-Light primer strikes
1) How are you priming the cases? If you aren't fully seating the primers, it can cause this problem.
2) Have you used the same batch of primers in another rifle with no problems?
3) How do the primer strikes that work look?
4) Has it happened at all with brass that has already been fired in the rifle? New brass will necessarily have greater headspace than once fired, some of the firing pin force can get 'used up' in moving the brass forward a couple thousandths. If it hasn't happened with brass that has already been fired, then this is a likely candidate.
Along with the things you mentioned, your gunsmith should check how much the firing pin protrudes, if it is a bit short, the same thing can happen.
If some is good and more is better, then too much is just right.
