I don't know anything about the NEF/H&R .35 Whelens, but I have had very good success with the round. I have have a Remington 700 Classic in .35 Whelen and have taken deer, bear, moose, caribou, and coyotes with it. My rifle shoots well with the 225 gr bear claws in Federal Premium. Federal has just started offering the round again, so supply shouldn't be a problem.
