building a 338 Lapua and would like it to be mag fed. from what I am reading you cant feed 300 grain pills through a mag due to length. If this is the case how small do you have to go to be able to use a mag, 285gn., 250gn? would really like to use 300's but don't want to lose the case capacity by seating them deep enough to mag feed. any help?
