THS78,
I agree with both HALCON and PRO-LINE. To say that the .35 Rem. won't kill an elk would be false, but I wouldn't use it. I'm not sure that you would get the penatration needed, even at 50 yards. Bullets available for the .35 are pretty fragile for elk. I dislike agreeing with Boddington, but he called it pretty close when he said the .30-06 with a 180 grain bullet was his personal minimum for elk. I hope that this helps. Sorry to be such a spoil sport.
