RE: NEF ejection issues
lol!! before i even openned the thread I thought to myself I bet its a .243......
from experiences with NEF rifles this seems to be most common in the 243 caliber barrels. the only way to completely fix it is have a gunsmith polish out the chamber, NEF rifles seem to have really rough chambers and the demensions of a 243 case dont help this any. Something else you may try is different brands of ammo different brands have different alloys in their brass and in most cases helps this 10 fold from what ive seen nickel cases and winchester cases seem to be the way to go. good luck
