I have not shot the ultras but have extensive history with the old Core-lokt and if we compare the untras to them the picture is very positive.....it's a bonded core-lokt and I'd not hesitate to use them for elk at all.

However how they stack up against a Interbond, accubond, Northfork, TBBC, Swift A-Frame I have no clue. We're talking about the cream of the crop here.
