I have been having trouble with CCI Small Rifle Primers BR-4 . Having a lot of miss fires . I have put a new firing pin spring in and still having the problem , but never with Remington or Federial Primers . . Anyone else having the problem ?
Did you check the firing pin tip? They do wear and small amounts break off?????
Or you could be bumping the shoulder too much. I did this using wrong shell holder. Had 2 of the same number. Mixed them up.....
Even though you put in a new spring, that does not mean you have enough spring pressure.
Some actions, older Farleys in particular, were notorious for having too light of spring pressure and not enough firing pin travel.
I always go by Kebly’s recommendation of not less than 23 lbs of static pressure and .230 inch of travel.
You might check that.

make sure that you feel the primer bottom out into the pocket and put a slight crush on it to seat the primer. He suggested also that I consider uniforming the primer pockets. I did both and haven't had any issues since. JME. WD
I think I found my problem , I was NOT seating the CCI BR-4 primer deep enough . I never had a missfire to day . The gun I shot was a XP100 built in 1974 and the guy I bought it from shot many matches with it and I bought it in 1980 and shot it in some matches along with lost of groundhogs and red wing black birds and in 2021 it will still hold under 1/4 inch . I'll bet not many can say that and today it only took 7 patches to clean the barrel .
See there by the number "8" is a bullet to compare to the 4 shot group is .035 , but as always I can't keep all 5 shots in the same hole . is that becouse I don't have a bore scope , barrel not clean enough ? I think it is just me .
