I'm trying to take my reloading to the next level by neck turning my brass. I'm having the rifle built now in 300rum and it won't have a match chamber but I just want a consistent pull on the bullet. SO.... my question is.... I'm measuring my new Remington brass and they are all under the shortest case length listed for the cartridge. Should I trim them to a consistent length even if it's too short? It seems like it will have a pretty large affect on the neck turning depth. What does everyone do in this situation?
