Good Read!
Have had good results with 160 gr. Fail Safe loads in my 280 Remington. All shots were close on 4 bulls taken (3 by me and 1 by a friend) with this load. Never recovered a bullet. Two were one-shot kills, two took follow up shots that in one case might not have been needed. Broke shoulder bones on two of the bulls. The exit wound looks like a 4-blade broadhead passed thru the animal. These rounds were sold in the Winchester Supreme line of ammo and have not been available since the late 90's. I'm down to my last 1 1/2 boxes of these darling nickel plated cartridges . Anyone seen a box or 2 these on the back shelf of their local gun store? A hand loader who stumbles on these bullets could do much worse.I think the velocity thru my 22" barrel was 2805 fps. IMHO this bullet would stand up to higher velocities and be great elk medicine in any 7mm Rem mag, WSM, STW, SAUM or the like. I think the E-tip has some features of the Fail Safe incorporated in it's design.
More bullet than you might need for deer? Made my best off hand shot (in tall grass) with this combination on a Montana Muley. Took out his heart at 175 yards with another pass-thru that caught little bone. The buck staggered and fell with in 30 feet of being shot. Good accuracy resulting in little meat damage.
Have since found a Federal 160 Grain factory load that shoots lights out in my 280 Rem Mt. Rifle. This 160 Gr. Accubond Federal offering is now also discontinued. Dam the luck! I have no experience to date shooting elk with this load. So far have recovered two bullets on three small bodied whitetails that did not travel far after being well hit. Very accurate, producing the tightest groups in the 20+ years I have owned the weapon. With shot placement being the biggest factor in a clean kill, I suspect it would be fine. For the big boned Oryx, it might not be the best answer.
