AICS binderless mags,whether in 308 or WSM,will do same/same. Pinch WSM feed lips or open 308's and you are there(I've done it both ways). Nothing to it. Hint.
What are you wanting/hoping to do with the 284,upon said platform? Due case length and bullet diameter,it's a rather poor choice in a AICS binderless housing. Were you to add particulars,it'd be easy to point you on the right path,as I shoot a "few" chamberings on 700 S/A's with AICS DBM. Hint.(grin)
I can't think of an application,where the 284 Win connects any fhuqking dots,though it's always fraught with heavy concession(s) in said blueprint(s). Hint.
6-284 in AICS binderless here. Hint.
Just sayin'.
