I used my little NEF .243 for a whitetail deer hunt in OK this last season and loved it! But, when working up a load, I found that I had to have full length re-sized brass that was really clean before it would promise not to get stuck in the chamber. I dont mind it with my .243 but what I am worried about is that if I get this 270 or 280 barrell for it that it will jam in there during a deer hunt. I heard the .243's have an inherent problem with jamming, but I dont know if this is true. Tell me what you all think and know of this. Does your NEF have a problem ejecting brass? EJ
