Ray, these common medium bores are surely a 300 yd. gun aye?:
338 federal, 338-06, 338 RCM, 338 win mag, 358 winchester, 35 whelen, 358 norma, 9.3x62, 9.3x64, 375 Ruger, 375 H&H.
My 9.3X62 wears an FX-II 6X36 with LR reticle. It works pretty well.
Luckily with mine both the 250 Accubond at 2650 fps and the 286 NP at 2475 fps have the same point-of-impact at 100 yards, and are zeroed to be 2 1/2" high at that range. The zero is at 225 yards with the Accubond, closer to 200 yards with the NP.
With that zero, they are never more than 3" above line of sight. With the 250AB the dots are on at 300 and 375 yards,the post at 475. With the 286NP the dots are on at 275 and 350 yards, the post at 425.
