i am working on a 260 build project and i need to order my reloading stuff i bought the redding competition bullet seater. but i need to know about the sizing dies. full length or just neck size. If you suggest neck size how do they work?? i have only full length resized in the past for my other calibers. i will be using 260 brass and this is a bolt gun. i would like to here all opinions if you would like to share. my barrel just got ordered it will be a brux so i have 4 weeks. but i like to stay ahead of the game.
