Well my 25 creedmoor build is coming along now and I was wondering about brass. There's two companies who make head stamped brass for the 25. Alpha munitions and Petersen. I was wondering what might make a guy choose one over the other. Anybody have experience with these that can shed some light? The Petersen is about 5 dollars cheaper per 100. What are things to look out for with each one? Pros and cons?
