Primer failure with federal ammunition
Blown primers and hard ejection are clear indications of excessive pressure. If these are handloads you need to back off on the charge and possibly make other changes in your load. Check a good loading manual for reference.
If they are factory loads you perhaps have a headspace problem or the oal with that particular bullet is too long for your particular rifle, jamming the bullet into the rifling, and not allowing it any "jump space" or lead.
1. dont fire anymore of that lot of ammo, and contact federal.
2. check with a qualified gunsmith, have headspace, and bore diameter checked.
3. if your knowledgable in smoking the tip of a bullet, check for lead, or have this done by a qualified gunsmith.
