I am redoing my rem700. I have a boyds stock and have ordered an atlasworx bottom metal and an accuracy international 308 magazine. From what i understood, 22250 can feed from a 308 mag. I received the mag yesterday, and the first few rounds fit perfect, but when the mag is full it looks like the rounds are going to nosedive back into the mag. I came to the conclusion that this is from the taper on the shell. Can i adjust the feed lips or is this a waste of time?
