Thread: Norma versus ADI .308 primers

Hi Guys

I'd appreciate some feedback on this. I have a .308 load for A Max of 45.2 gn AR2208. Getting 2580 in a 19.5" barrel and very accurate. I've been loading it in two different cases, ADI and Norma. The primers on the ADI cases are much flatter than Norma. I understand ADI is a tougher case so perhaps that makes sense. I'm a little uneasy about the degree of primer flattening on the ADI cases with that load and am considering retiring them and using only Norma, which kind of makes more sense anyway. Primers are Federal LR 210. Do the primers in the ADI cases look too flat to you? There's a row of Norma at the bottom. You can see how different they are. Just wondering if I'm over reacting or not. I suppose I could back off the load with the ADI but that's all getting too complicated. I guess having two brands of cases is just not a good idea.

Cheers.
