By the way, who makes a .30 cal 240 grain FMJ? Also, not to overANALyse a just-for-fun question, but depending on length of the actual bullet, a 240 might require a tighter-than-standard 1/10 twist, something along the lines of 1/8 or 1/9.

; I think an 8" might work. I do recall the typical 10" twist wasn't too hot when the 250gr. Barnes were running around the moose woods here with some guys. Accuracy was quite poor, except in the magnums which, of course, drove them somewhat faster. The 2,200fps or 2,250fps of the '06 was deemed to be a bit too slow for these pencils. If you want to compare this with the .318Rigby, don't, the .318 shot a .330" bullet, I believe and twist requirements are, of course, slower for the larger bore, shorter bullet.
: A 'good' 250gr. solid .30 cal bullet 'should' out-penetrate any 480gr. or 500gr. .458, 500gr. .470 or 520gr. .50 when they are all driven at the same velocity as penetration, given identical bullet construction is dependent upon stability inside the target material and sectional density alone. Is this now saying that the '06 is 'better' because it penetrates more deeply? Is this deep penetration the only criteria to establish a ctgs 'desirability' on dangerous game? I think not to both.
: Then, to compare the suitability or a 250gr. .308 bullet from an '06 against a 400gr. or 450gr. .458 bullet from a .45/70 - why? what does this prove, asking a bunch of guys
who haven't used either, which they would prefer.

Good points Daryl.

The .318 Westley Richards is basically a .30-06 with a 250 gr bullet in .330 calibre.

Bell used his .318 extensively for elephant with FMJs, but then I don't like quoting Bell as he was such a remarkable man.

However the .318 was a very popular chambering.

Compare this to the .45/70 and perhaps the equivalent Imperial .577/.450 which was quickly superseded once better cartridges were available.

IMO in hunting dangerous game, calibre size is nothing without adequate penetration.
