Man, Having a heck of a time with some brass I am doing prep to. Been de-buring the primer holes and trimming the brass today. I have about 2500 to do. All I can say is that Remington is giving me the most trouble. The flash holes are all over the place as to diameter and the flashing on the inside is huge compared to many many types of brass. Federal seems to be about the most consistent so far. My hands are killing me right now so that is the meaning of the post. Taking a break.
I think I am going to order a 3-way trimmer for the 308. I have one for the 223 and it works really well. It should save on the hands a bunch.
