All I can say is that I was very impressed with the entire lineup of Vortex/mar-den heads. They are larger, but the " smaller" two inch heads penetrate as well as most 3 blade heads with cutting diameters of 1 1/2" or so. As for strength, even the larger heads proved far more durable than I would have exspected. The 100 grn Mini-max steel solid is one super tough head I feel would be very suiteable for elk with the right setup. Frank You should look at the 2 3/4" 125, now I know it' s 25 grns heavier than you want to shoot, but Man that' s one big head!![]
