I just got some Winchester brass in 7mm Remington Magnum that I had on backorder for the last few months and am pretty disappointed. There were many with heavily dented necks, but the larger issue is that a majority of the flash holes are misformed. When you look like down at it it looks like looking at a basketball next to a baseball. Even after deburring the flash hole it still looks misshapen. I am planning on using the brass for a mule deer hunt, but I also will be using it to shoot long range (600 yard) for fun, so I want it to shoot. Any suggestions on brass manufacturers? Are there better manufacturers or did I just get a bad lot?
