I've always regarded the 270 Win a scaled-down, light-recoiling 300 mag. Similar trajectories and killing power.
Before he died, I corresponded a bit with George Hoffman, Professional African Hunter, and the developer of the 416 Hoffman (which eventually became the 416 Rem Mag). His elk rifle was the 270 Win. All his nearly 50 elk were taken with the cartridge he told me.
Daughter #1 will be using a new-to-her .270 for elk this year. 150g ABLR @ 2910fps. Fairly mild recoil, 2000fps and 1500fpe to 740 yards. Given her comfort range of 400 yards I think it will be adequate. Hope she gets an opportunity to prove as much.
CH, how are you getting 2000FPS/500 Ftlbs of energy at 740 yards with a BC of .543 (Litz tested in a 1-10 barrel) and a 2910 start speed? I am getting a retained velocity of 1768 FPS and 1041 Ftlbs at 750 yards? Not questioning your load it just sounds a bit high. I ran it through a couple of ballistic calcs and can't make my numbers match yours.
I used the Nosler value of .620 and 7000 feet altitude. Ballistic calculator was 'Point Blank', the original version. Using the number you attribute to Litz (.543), I get 2124fps and 1502fpe at 650 yards.
Regardless of actual B.C. value, we verify drop at actual ranges to 600 yards. During load development I was shooting sub-half-moa groups at 100. Pretty sure the load will work at her comfort range of 400 yards (2409fps, 1933fpe @ 7000 with Litz B.C.).
I appreciate the question. Should have specified the parameters.
