RE: Need Help with Groups. TOO BIG!!!
Tryed any good (federal) factory loads thru it? I got a 270 that loves a 4064 load but not other gun does. What is your load. I am sorry, as I have limited experience with NEF. Maybe take to a gunsmith to do a quick check on headspace. Not sure. If it was a bolt, there is all kinds of things to look for. When you say proven loads, is this in another gun?
