Let me guess you brass was once "superformance" 178gn loads.Soon after it came out ( superformance ammo ) a lot of guys that tried it had problems from the get go.So Hornady now crimps the primers in on the 178gn,not sure about the 168gn.
Just as said above use your chamfering tool and thing's will be OK.
The brass is really good for I get to pic it up at the range I us.Been loading it with great accuracy with a 175gn SMK and varget.Sometimes I pick up crimped in primers sometimes not.
with 5-600 pcs of brass you want have to buy any soon
I am on the 4th time with some and it stilll looks great.Stay away from hot loads and anneal the necks after the 4th everytime and you'll be Happy Happy Happy
