Since you have both brands of dasher cases fire formed in your chamber plus fireformed Laupa. Find the weight and water capacity of all 3 cases and post the results. Several samples of each will show if there is a large variation in capacities, of each brand... resulting in pressure signs of the smaller capacity cases? Or case head hardness between brands? Hard jaming of bullets into the lands could cause case head swipes too depending on neck tension, with the bullet. All my new Alpha brass is run through a Wilson mandrel die so the bullets seat with the correct tension. For me they are too tight right out of the box.If you have tried both Petersons and ALpha OCD brass what is your opinion after testing?
I have been shooting Petersons brass with a reduced load from Lapua brass running right at 2980 and still seeing swipe marks but the primers show no signs of pressure.
