I swapped my old .270 out for a .308 barrel. Feeds great. Extraction / ejection is another story. After a shot if I yank the bolt back quickly the spent case will eject properly. If I pull the bolt back too slow, the case will jump off the bolt extractor & sit on the follower or next round in the mag.

One of those things ya get used to...
I believe on of the guys has a cure for it by doing a little modification to the extractor or ejector, as I recall.
I think, anyway.
