: Albertan has a point - based totally on SD and velocity. paper specs rarely produce results in accordance with the numbers, as 9.3x57 found out in his test media.
: 9.3x57 has also found out the 300gr. .375 swaged to .368" and fired from a 9.3 rifle will out penetrate any non FMJ .338 mag load out there and just recently published those results on another forum. Paper specs don't tell the whole story- hardly ever do.
: I have a lot of respect for the 8x68 and similar .338 mag, .35 Whelen, .375 Whelen Imp, 9.3's and .375's. Out to 300 yards on moose, there is little difference in killing power as they'll all drop the moose close to impact if used properly. They'll all leave the bullet underneath the hide on the off side if you want, or exit if that's what you want. One merely picks the appropriate bullet.
: Arguing which round is better based on a couple numbers of sectional density in a day when modern premium bullet designs have negated that system's validity, is non-productive and in error.
: The .35 Whelens I am familiar with run 2,250fps with 300gr. and 2,600fps with 250's. My .375Imp Whelen gets 2,470 with 300's and 2,675fps with 270's. They give up little or nothing to factory .338 Win. Mags. in paper ballistics, but paper ballistics are only the start of the equation today, not the answer. The results are what matters.
; Famed writer and African Hunter, the late Finn Aagard once wrote he saw little if no difference on the African game he shot between the 9.3x62 and the .375H&H. He was using 286gr. at 2,340fps in the 9.3 and 270gr. at 2,700fps or 300gr. at 2,560fps in the .375H&H. On paper, they produce a trememdous difference, but the animals he shot couldn't read.
