Moisture In Primers? Failure to Ignite

Boooooo

If your chamber is oversized, you might be sizing them but some still dont get down to spec for your gauge after a firing. If some cases stretched more, weren't lubed the same, had different levels of springback, or press was operated a little different you can have slight differences in dimensions after sizing. I dont think i've ever used a case gauge because generally speaking i only care how a case fits in the chamber it's being fired from.

This would be on my short list to check out. If the chamber is too long (excess head space) for the brass thats going into it the momentum from the firing pin is being consumed pushing the case into the shoulder of the chamber instead of smashing the primer cup against the anvil. Bergara will need to have it shipped back to them to discover this for themselves.

If you get a hold of a no go gauge or go to a local gunsmith with one and put it in there you could confirm that the chamber is too long for spec. If this is whats going on I would expect virgin cases and factory ammo to have the most trouble igniting. And brass that has been fire formed to your chamber to measure longer from case base to shoulder using a case compactor tool for your calipers. If you neck size this stuff I would expect it to fire reliably. The gunsmith may be able to screw the barrel in more or adjust the headspace depending on how your barrel attaches to the action.

Bottom line for this issue: bergara can be expected to be cheaper to fix, local gunsmith can be expected to be faster to fix.

To your post higher on the page if you pushed the shoulder back too far the FL sized brass would be worse about this than the factory loads and virgin brass. Do you have case compactors? Saw you don't... they take some guess work out of this situation. How do you set your die to achieve your desired shoulder bump?
