I'm considering having a gun built is either .280 Rem or AI.I don't currently re-load however since .257 roberts (myfavorite deer gun) offerings are becoming fewer and far between (not even core-lockts at gander mt.) I'm considering it more and more. I also didn't see a huge selection of .280 rem's either. Assuming I go ahead and start re-loading or take my friend up on his offer to re-load for me (I supply dies, brass, etc.) which one should I get for hunting purposes? The gun will weigh around 6.5 lbs. Thanks.
