I have a batch of cci large rifle primers.
The gun I’m using them in I’m getting 2 fail to fire in every 20 rnds.
The primers show a little shallow dent. The next firing and the dent is very little deeper if any and doesn’t fire.
The other primers fire well.
This is in a 30-30.
I checked the shoulder length from base of rim to a point some where with calibers and a block with a tapered hole in it.
The total variance was 0.03mm or 12 thou.
The firing pin extrudes well enough.
Have I got a batch with some harder primer material.?
I may try and extract the primers next time around and see if they will fire in a different gun.
Thoughts?
Things to try look for?
Maybe my ancient meckon/ lee red plastic primer tool has had it’s day?
Thanks
Bruce
