I am having an issue with light strikes. This is a known issue with some guns but mine is a newer manufacture well past when all those problems were supposedly fixed. In 400 rounds, I have had 7 light strike failures... 4 of them in the last 40 rounds.

Now, granted, it has happened only with one obscure brand of ammo but I have fired 500 rounds of that same ammo without any problems whatsoever... The gun has fired all other brands that I have tried so far without problems.

I want to compare with a couple brands of commonly available ammo that are known to have hard primers.

I don't know 'fer sure' but I would guess that NATO surplus and maybe products that use CCI primers might be candidates to try. What about S&B, Fiocchi or Privi Partizan? Any others to try?

What are your recommendations and what basis do you have arriving at that conclusion?

all answers appreciated
