mrlizzard, I also replied to the crud ring post.
I was not aware that you were experiencing mis-fires as a result of the primer itself not firing.
Could be you have a bad batch of primers.
Try a different MFG Winchester, Remington, etc..
If still misfiring primers;
Firing pin engagement/alignment/issue here.
Potentially dangerous situation - as whenever a misfire coccurs we change our position from pointing it at an intended target while handling the weapon to inspect the misfire. During this moment the weapon can discharge resulting in an accident or firing the weapon in a non-intended direction.
You should not have to switch primers to find one that your weapon will fire.

If possible, return the weapon to your point of purchase for an exchange.

Or Call CVA.

Don't hunt with this weapon if still misfiring.

Best,
