Thread: Primer seating problems

Hi team. Recently having some frustrations in regards to seating primers. I have Norma, alpha and Hornady brass. All new and unfired. Recently, due to the shortage of federal primers I have changed to white river energetics primers and cannot seat the primers below flush. They are protruding between 5-10 thou on all brass brands. I cannot and don’t want to crank any harder on my press for fear of bending the case rims or the shell holder. It’s obviously throwing my C.O.A.L all over the place. Very frustrating considering Norma and alpha brass is not cheap. Nor is changing primers to another brand. I have tried to seat ginex, WRE primers, Winchester and federal. The federal and Winchester seat quite close to flush but the calipers say that they are protruding by 2 thou. Both the norma and alpha brass pockets are so tight I cannot get a uniformer into them to remove material from the bottom. I am hoping it’s something to do with the press as it’s cheaper to replace than all that brass and my stock of primers. Any tips on trouble shooting?
Cheers.
