Tony,
I'd have no problem with a new rifle bought online, but a used one would need to be checked before you transfer ownership and I'd be very cautious. The H+R/NEF guns I have, .223, .243, 7mm-08, 45/70, and 20 guage shotgun, have not shown any problems with shell ejection. The triggers seem good for hunting, but I want to lighten up the varmints trigger a bit. The only other problem seems to be the forearms pressure on the barrel, and is easily cured by adding a rubber O-ring where the forearm screws into the barrel.
