At 600 yards:
.270 Win/150 LRAB @ 2910fps,
254 yds = zero point
300 yds = MPBR
52.6" = drop
2234fps - velocity
1662fpe = energy
15.5" = drift
17.7 ft-lbs recoil
7mm RM/168 LRAB @ 3047fps,
266 yds = zero point
314 yds = MPBR
45.6" = drop
2377fps - velocity
2108fpe = energy
13.7" = drift
27.9 ft-lbs recoil
your 150 LRAB (.591 BC ) and 168 LRAB (.616 BC) velocity-energy figures for 600yd, seem out of whack.
after running those bullets through a few different ballistic calculators, I consistently get more like
2037/1382 and 2180/1773 , respectively.
7-mag also offers option of 175 LRAB(.648 BC)
2800mv, delivers 2017/1581 @600yd.... 20.60 ft/lb recoil (8 lb rifle)
