From what I can gather, if I install a 22-250 barrel on a 308 short action with double feed internal mag box, it might feed ok. Then again, it seems it might not. Am I correct in assuming if I run into issues with feeding I simply drop in the shorter box and follower?

If that is the case, anyone have the part number for the 22-250 box and follower? Or where can I find those numbers, please?
